Single Phase Contactor - Connections Explained, Application plus the Current in the Coil and Load

Matt and Joe show how a single phase contactor can be controlled by a 1 way switch and be used to turn on many heavy current drawing loads. We see how many lighting points say in a factory can be turned on by a simple light switch via a contactor.

I sadly look forward to these videos whilst lying in bed. The wife doesn't like it. Ooops!

[@davidmanning5874]

THANKS FOR SHARING LADS I LOVE WORKING WITH CONTACTORS AND RELAYS GREAT VID FOR LEARNERS

[@luismorelli3943]

Great video, explained well👍🏼👍🏼👍🏼

[@brianoceallaigh8714]

Well explained guys... And another very informative video...

[@GSHElectrical]

Hi thanks for the positive feedback Gaz 👍

[@marshallluddite]

Excellent explanation thanks, going back to watch the other vid you mention now.

[@georgereynolds124]

Good video 👍🏼

[@felixajapong3556]

Thanks very much for this video.

[@LordRedDragon]

it would be wonderful if u provide a SLD at the end of the video or when u start explaining the circuit. thanks for another wonderful video

[@GSHElectrical]

Hi. Thanks for watching and commenting we will try and continue to improve our videos 👍

[@user-yh4kl3hx2o]

Wow wish i had youd knowledge

[@bryansmith1422]

It would have been nice to see the connections properly in the video but unfortunately I could not, although I understand the object was to see the small current v large current which I now understand, the cables in the video made it hard to see what was connected. I was more interested in the 5 connection points on the device (assuming 5, not sure?) and more info on its practicality. Love your video's Thanks for Hours and Hours of learning (I'm only trying to expand my mind "I'm not an electrician, or even in training, but I like the science of it all) Any chance of a simplified video on the same contactor because I'm very interested ? Thanks again! Love your channel keep it up! Kind Regards Bryan

Yicheng Automation is a very professional factory in automation equipment fields. them manufactured many automatic assembly line for the switches and sockets manufacturer.

[@dansheppard2965]

Where would you typically house the contactor box? Here you've got it near the switching point, which I guess is great for testing, maintenance and the opetrator hearing that clunk (and in the test rig for the ammeters). I can see you might sometimes want it near the distribution board to keep the wire runs short of the load circuit, avoiding looping them down. Is there something in the regs about safety etc that I've not thought of? Maybe it doesn't matter, and it goes wherever's convenient?

Poor Gaz getting left out

[@connordickens2617]

👍👍

[@user-od3rl5mc]

In some scenarios access to a secondary circuit may be limited. Could a single MCB feed both the switch and contactor?

[@aleoluwagbemiga2281]

Please I will want you to do a video on how the contactor can be connected with a relay and timer

[@AllenGoldsmith]

can those circuits be fed from different phases i take it they can as they don't come in to contact with each other?

[@GSHElectrical]

Hi
th-cam.com/video/bkboBItqFXE/w-d-xo.html
This link may help.... thanks for watching Gaz👍

[@ashmanelectricalservices4318]

Yes, they can be fed from different circuits, different phases even different consumer units.

[@sandman873]

Is that 3 neutrals at the contactor? Is one of them connected to the light?
On the 1st contactor video it went straight back to the board that's why ive asked. Cheers 👌

[@ashmanelectricalservices4318]

One neutral is for coil, another neutral is from the consumer unit to the incoming side of the contactor and the last neutral goes from the outgoing side of the contactor to the load(s).

[@sandman873]

@@ashmanelectricalservices4318 thanks pal

[@patdbean]

Dose having an internal cell for one network (say o2) within a building like a pub, overpower the coverage and weaken the coverage from the other networks?

[@supersparks9466]

I think your barking up the wrong video

[@ashmanelectricalservices4318]

Where would we be without electromagnetism... 😀

[@kamranhassan2061]

Wiring diagram?

[@Webbster77]

I didn’t think this was explained to well… what’s in a1 and a2? What’s in the top and the bottom of the contactor

[@user-yh4kl3hx2o]

A1 feeds the coil A2 is neutral to smooth the circuit

[@balasuriyage]

Bit of a silly joke at the end AH?

[@GSHElectrical]

🤦🏻‍♂️
