I am an electrical estimator and I am quoting a telecom testing/assembly lab with 264 outlets of different voltages and frequencies.
All the outlets are rated 20A.
222 outlets are standard 120V single phase and 208V single phase.In particular my question is regarding 42 outlets that are at 225V single phase, 50Hz frequency.
On my drawings they show a power/frequency converter, it has an input of 30A at 600V AC, 3phase 60Hz.
The output (as shown on the drawings) is 225/390V AC 3phase at 50Hz.
This item (converter) feeds a panel, and the panel feeds the 42 outlets. Each outlet is on it's own 20A circuit breaker.
My questions is; Does the frequecy affect the insulation or size of the wiring? Typically a 20A outlet is wired in 12AWG. Does the frequency have any effect on the insulation or wire size?
Any help on this matter is appreciated, thanks in advance.
