[@ratheismcirclejerk]

I’m not an electrician and know literally nothing about electricity. But your videos are awesome. You are like a lawyer with this stuff. Love your passion

Best explanation; better than Holt or Stallcup - thank you.

[@alexbemis2656]

I agree

[@DM-mb9jh]

I want to thank you for taking the time to make these videos. I like to continually learn and you do a great job of explaining and teaching. Thank you!

[@iaov]

Thanks.Well done as usual !

[@ericpolk9004]

okay how about this one if your up for it
Can you run “Intra - Building cable” in an elevator shaft?

[@danieljuneau229]

So can I put a door bell wire in the same drilled hole as a 120v circuit that’s for the transformer?

[@RadwanAl-Shaer]

I thought Class 2 circuit protects from shock and fire, but class 3 only provides protection from shock, but not fire. class 2 installed in a wet location can become class 3

[@RyanJacksonElectrical]

@@RadwanAl-Shaer Nope. Take a look at the definition in Article 100.

[@RadwanAl-Shaer]

@@RyanJacksonElectrical In my comment above I meant to say class 3 provides protection from fire, but not shock. I just read the definition. class 3 circuits require additional safeguards to protect from shock.

[@ericpolk9004]

I can’t find a definitive answer to this question do you have any thoughts?
CAN I RUN 300 VOLT COMMUNICATIONS WIRE IN THE SAME ENCLOSURE AS CLASS 1 600V CIRCUITS IF I HAVE A BARRIER RATED FOR 600V?

[@RyanJacksonElectrical]

Yes, if you have a barrier.

[@ericpolk9004]

are network cables like cat6 considered class2 ?

[@RyanJacksonElectrical]

It depends on the application. Class 2 is a circuit type, not a cable type.
