- เผยแพร่เมื่อ 14 ต.ค. 2024
- In this video you’ll see how I updated the wiring to an old detached garage in Westfield, New Jersey. Three new switches, three new receptacles, three new lights, EMT conduit, and a pair of junction boxes for convenient wiring methods. All new wiring with 12/2 MC cable and metal outlet boxes.

The old no. 14 wire on knob and tube would carry a lot of current, being in free air. Inside walls it is often in good shape, but not so when it comes into a box or just through diagonal holes in a board with loom above the old light fixtures. Insulation there is usually pretty toasty.
I ALWAYS look at the Kelvin rating on lamps!! Started off in high school doing technical theatre work, studied, lighting design and college, and owned an electric sign company for 10 years - so proper kelvin rating is important to me!! 💡
I enjoy your knowledge and the creativity of your work. Thank you for sharing.
Ron, so cal electrician here. I hate using bags, but i just started using the VETO pro pac waist apron. It makes my life easier.
Feeling lots of Milwaukee pride watching this. From Milwaukee and also a proud user of so many of Milwaukee tools. But I will admit I'm a big fan of Makita as well. I've done tons of ethernet fishing and wiring, but learning more about electrical work as I restore and update my 1940s house. Appreciate all you do to make your years of experience and knowledge accessible to more people.
You are my kind of guy. Running MC in exposed areas is the way to go.
Very informative, thanks!
Great discussion about Kelvin temperature. Don't forget color quality as well!
Extra points for EMT & 1900 boxes:
Garage stud walls and open overhead is a perfect example of where conduit is the best.
I like how you fabricate backer boards in your work too, "do it right the first time"
as callbacks are a money pit..
Thank you.
you should make a video about tube and knob, explaining what it is and why it needs to be replaced. show the fragility of the old wire and how fires are started by it.... seeing it still around in 2023 is crazy! I thought by now it would all be gone....
The amount of work and costs to remove it... you should understand why it's still around
Thanks Ron for sharing your knowledge with us.😊
Great work Ron. I'd trust you to wire anything in a heartbeat. I'm rewiring my 1933 original wired colonial so I can use some good advice!
That said, I was a OSHA instructor for a while and if you can turn off those circuits or wear insulated gloves, I would always recommend it. You wouldn't believe how many electrocutions we watch when we go through the instructor course. Hell, we had an electrician there who dang near taught the course.
I don't even trust a blow dryer near water connected to a GFCI anymore. They're good but still not fast enough response time to mitigate the chance of heart failure from what I understand.
Sorry, I ranted again 😂 God bless, and great work man!
Looks relaxing
Very!
I’m look at temperature all the time on bulbs and I tend to like 2700 to 4K at the most. Some of my neighbors are installing daylight bulbs and insanely bright daylight flood lamps on porches and garages. They literally hurt my eyes at night and don’t understand why people do it. I glad you aimed the floods so they aren’t pointing aimlessly down the driveway. Beautiful job and love the metal.
Agreed. Soft white for everything but the bathroom vanity, garage interior, attic, and utility room. Our 1933 home would look out of place with daylight bulbs anywhere else. Unfortunately many of my neighbors don't think the same way.
Nice job Rob
I like all the Milwaukee boxes and tools
Great atorage
Nice work, Ron. It's interesting to see the variety, not just service upgrades.
Thank you very much brother. We have a 1915 home. There is a wood panel outside. There is still knob and tube coming from that old wooden panel into a old shed outside. I cannot believe it still works. Then we have a yes I know it’s scary, federal pacific panel in the cellar with aluminum wiring. Could you get any more scary. I am currently working on it with a journeyman electrician friend of mine to eliminate thus.
Great knowledge brother
Thank you for sharing your knowledge and wisdom. Much appreciated.
You’re welcome Vince.
Awesome videos I’ve just recently started uploading electrical videos too because of you ! I love you work
That’s great to hear! Work hard and try to make good videos. Take your time but don’t over think it. Just hit record. Good luck to you!
Oh nice work. Love the EMT, MC cable, and steel boxes. Good materials for a garage. I used NM cable and boxes in my garage, but the commercial grade materials are superior for exposed work for sure
Thank you. It’s a little more labor intensive but worth it.
@@electricianron_New_Jersey If the garage already has drywall up...what do you use to install outlets at the workbench height and for a ceiling outlet for a garage opener? Metal or plastic? Is NMB ok to staple to the drywall or is a strip of wood needed? or is MC required? as I understand it, the wiring cannot be subject to damage but is the wiring subject to damage if it is set back 24" (countertop/workbench depth). question being....no conduits needed?
Doesn't the 2017 code require GFCI outlets in garages?
I’ve got that same old Edison-based box in my 1920s house too. Don’t know if it had fuses in it at one time but in later years it also became a j-box and recently we just bypassed it altogether. I should probably rip it out but it’s got a 2 inch (?) rigid conduit connected to it and it’s in a tight space so it might just have to stay there forever.
Good discussion on color temperature. When they first went to compact flourescent it was difficult to figure out what temperature to get. LEDs are better. Also now they put lumens on the box. I had a friend replace a bunch of 4 foot flourecents in her kitchen with round LEDs. Then she wondered why the kitchen was so dark. She about halved the amount of lumens. Not sure about others, as I get older I need more lumens.
@16:02 Here in PR we have to pigtail to receptacles cause of fires. Many have melted so they made it part of the "complementary guidelines" to the NEC.
Do your best work. Always.
@@electricianron_New_Jersey Keep em coming, "in the field videos" are the best.
Just started watching ur videos,absolutely love them .
Note:
For anyone working above or below a motorized garage door be sure to secure and power down/lock out tag out the operator. Accidents are very common with this mistake being made. On the note stay safe skilled workers!
Just unplug the cord.
Great video, new sub. I appreciate that you are helping people keep safe. My house is 123 yo and I haven't been able to get someone to even quote getting my k&t out. Its a tough dirty job in the old houses but it needs to be done at some point.
It’s costly because we need to open walls to fish cables.
I love how old wiring looks 😂
What brand of keyless lights did you use ? They look nice.
I’m a huge fan of MC cable - especially after mice ate through cables in my attic. I picked up a role of stranded 12/2 mc as it was a sweet deal at the time and like it a lot. You did a beautiful job as aways.
Leviton at the Home Depot.
Awesome job! Video mark 19:53 Using linesman's 9's is a very nice alternative to a razor knife to strip the ground conductor in preparation for bonding the j-box. Great video Ron.
The old farm electricians would just carry a box on 12-2 UF on their truck, since it could be used for so many situations. For MC I always use metal boxes and redheads on the connectors.
For this install I think you may be able to use a “ tight bite” connector I think made by Thomas and Betts. Those take up less room
Never heard of it.
why didnt you put tape around the receptacle terminals before you put it in the gem box? love the content
@@findinglove13 Not necessary.
Great video looking forward to seeing more
Thank you Fred! 👊
2700 K my favorite
If there’s only one circuit coming out to that garage you wouldn’t be sharing the neutral right? I’m just asking because I thought you said you were sharing the neutral.
Great video, Ron! Have you purchased Milwaukees new stapler? It saves a lot of time stapling!
Not yet because I have the Dewalt version from a few years ago.
@@electricianron_New_Jersey ah! I’ve used that one as well. Definitely one of my favorite purchases. Keep up the good work
An electrician who owns a hammer, you don't see that every day.
Use your safety classes especially working above your head. I once was driving galvanized nails above my head and had to go to the ER. A little flake of the galvanized coating got on the white part of the eye and it really hurt. The doctor removed it , no permanent damage. But you lose a day of work. 😢
Awesome stuff
Folks, he is right about the porcelin lampholders being better. Definitely do not use the cheap plastic Leviton lampholers that are sold at Home Depot. They have a very poor riveted connection which can become loose and arc creating a potential fire hazard.
Next time you feed a bell box through a wall, just use a short threaded nipple. Then use an appropriate transition fitting on the inside of the wall. Rain tight and smaller hole in wall. Been doing it for 30 years.
beautiful sir
I assume electricians get all their supplies from supply houses that only sell to the trades. Just curious that when you buy metal work boxes from those places, do they include the green ground screw? I assume the home Depot's and Lowes' don't as too many jerks keep stealing them.
Only weatherproof bell boxes come with the binding screw.
You're very good at what you do and a great communicator you should def teach some apprentices to keep the trade growing...
What do you think about wagos?
What year (about) was last year for knob and tube installation?
Great install Ron. Question for you, which article in the NEC would I find that says that there should be a main shutoff switch in a shed or detached garage. Thank you.
225.6 I believe. I’m on vacation and my NEC is NOT with me.
I live in a 95-year-old house. I have a name for my pain - knob and tube. It's out now but rewiring with plaster and lath and balloon framing is a nightmare.
It could be very painful. It takes a lot of time.
Do the garage door operators need to be on gfci protection?
From what I can tell, the receptacles for the garage door openers are in the load side of the GFCI on the wall. The door opener receptacles should be marked “GFCI Protected”.
Pigtails are old school , carry over from k & t days , vary out dated , more connections to heat up an go Bad .
How do I hire way a Great organized Electrician ?
I’m
Not moving to NJ 😊
why did you run two pieces of emt one will handle more conductors than you have
the skill saw on the trash can. Get some saw horses man
I would prefer to have more outlets and lighting in a garage and on it's own subpanel and also outside outlets.
Well, that might be an additional $5k.
What’s your labor rate ,I’m guessing this job about 1800 ?
How did you come up with that figure?
@@electricianron_New_Jersey it was just a guess a wild guess I bill out at 1200 a day with helper but I have friends who bill out more and of course some of the bigger outfits bill out much more . I just had a customer tell me that one of the bigger companies charged him $40,000 to replace the knob and two in his 1600 square-foot house I would’ve done it for half that
Hi Ron !
Do you need to use TR outlets inside of a garage?
Yes.
Universally required these days for residential work
I like daylight
other lights look yellow
And the daylights look like a dentist office.
Saw the one-handed work at the beginning: "Yep, it's hot."
Not an electrician, but I have enough sense not to buy the $0.60 receptacles -- a good $2-5 receptacle will have 20A internals for the 15A version, good clamps (not stabs!) for back connection , and plenty of brass for the pass-through.
not using pigtail on outlet you can overload outlet and the outlet can burn out and it's harder to find in fault finding a lot of the 15amp outlets are cheap and will only last year
I'm not worried Sam. The receptacles are designed and rated to be wired and installed like this. Are you an electrician?
Hogwash. Using the back stab connection might be risky, but using the screws it will last a very long time.
Why are you using 15 amp outlet and not 20 amp on a 12 awg?
@@Resist_JWO_1984 dual rated.
the original box was a fuse box why not a small breaker box in its place
i guess i missed the Knob and Tube section...?
That's a lucky break to have a relatively simple and straightforward job of replacing K&T in an open garage. Most of us face nearly impossible jobs in big old houses where all the old wiring is fully hidden behind wooden ceilings and wooden walls, or massive baseboard planks, or plaster-on-lath walls throughout the whole house. Which basically means such massive amounts of demolition and difficult repairs that it is probably better to just bulldoze down the entire house and start over.
"Most of us" wtf does that mean? Do you seriously think I haven't taken on jobs like that before? I've done whole houses - BY MYSELF.
@@electricianron_New_Jersey I never suggested or implied that you haven't done harder jobs before. All I said was it's a lucky break to get an easy one this time. Anyway, if you've done entire hundred year old houses, I guess besides electrician work you are also expert at patching hundreds of ancient plaster-on-lath holes (which can be quite involved) and patching hundreds of unattractive outlet and switchplate holes in 100 year old beadboard walls, (which can also be hard to match and repair). My comment was a simple observation, not an attack, and I did not expect to interact with you directly about this. I've hired many many contractors in my day, but I've never met one who is skilled enough or even willing to perfectly patch countless big holes in plaster walls or beadboard walls, and do a nice job of it. Clearly that type of repair would cost far more than upgrading all the knob and tube to modern wiring.
You still use wirenuts? 🤭🇩🇪
Home Depot kicked estwing out of there store estwing is made in USA and are 100 year old company and I live right across town from them.
nice person, but too much wasted time. i am sure You know what you are doing...but
