Wiring Method per NEC

Wiring Method per NEC

Wiring Method per NEC

(OP)
Hi, all!

I have 120V AC and 24V DC power sources to be terminated at a small control panel (installed locally).
Do I have to use separate terminal blocks to terminate above 120V AC 1phase 2 wire and 24V DC 2 wire (both are not shielded) cables?

Or can I terminate side by side on the same terminal strip.
That is if I have 10 terminal strip, if I use 1-2 for 120V and 3-4 for 24V DC will it be acceptable per NEC.

Please advice me which article of NEC spells this out!

Thanks,
Questforwiriing

RE: Wiring Method per NEC


No code requirements for separation so long as insulation of terminals and conductors are both greater than the higher voltage.



RE: Wiring Method per NEC

gigahertz is correct - for anything up to 1000V.

RE: Wiring Method per NEC

Suggestion: It depends what you have on 24VDC. The 120VAC may add some noise to it, which may be found objectionable.
