Insulation rating

[mstrlucky74]

Have two cables
one says 1 pair #16-24v
the other is 1 pair #16-120v
can you use a cable with 300v insulation for both or does the 120v cable have to be 600v insulation

I would guess that the 120 and 24 volts are the minimum needed for the cable.

Almost all cables are listed for 300V minimum. The cable listing just has to be higher than the nominal voltage of the circuit.

CAT5 is listed for 300V (but not for "high" power applications).
