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

[@alexbemis2656]

I agree

[@danieljuneau229]

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

[@ericpolk9004]

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

[@iaov]

Thanks.Well done as usual !

[@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.

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

[@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!

[@ericpolk9004]

are network cables like cat6 considered class2 ?

[@RyanJacksonElectrical]

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