PSU needing 2 wall outlets? - Page 3

post #21 of 36
12KW @ 240v = 50A.

Is that on one circuit breaker?

Combined, one unit is 8Kwatts the other is 4Kwatts. and they're on ... let me check... one is on a 20 amp and the other is a 40 amp (2 20's tput together)

That seems right:

8KW @ 240V = 33.33A x 125% = 41.67A (40)

4KW @ 240V = 16.67A x 125% = 20.83 (20)

Those are the breakers that trip, correct?

EDIT:

Wait a minute, 'two 20s put together'? That is not 40A.

I don't know if they auto sensor. They would require some type of smart ballast inside the PSU. But most are rated 120/240v.

No, the ones that are tripping are the ones with my PC's plugged in. Both are on 15 amp seperate breakers and both trip. Sometimes the PC's are pulling 7-11 amps from the wall though.

Something else is wrong then. If you're drawing 11amps tops on a 15amp breaker and it's tripping there's an issue.

OK, pulling 7 to 11 Amperes at the actual receptacles where the PCs are plugged in?

These are dedicated circuits or not?

If dedicated, it sounds as if the breakers are weak and need replaced.

If a common circuit, then other loads applied elsewhere on the circuit simultaneously with the PCs is probably causing the overload.

When I set up my computer room, I installed two dedicated 120V/20A circuits to a double duplex receptacle outlet specifically for my PC and peripherals.

That is the problem(one reason to go to 240 and half the AMPS used or), I would install another recepticle (or 2) but I have no free breakers to do so. Thats why I want to use the 240V wires in the wall and put the right recepticles on them. Just not sure which and what if new cords I'd need for PSU.

The wiring goes to multipule junctions split offs thoughout he house to different areas. Old wiring and not the best but I dont have the time to redo it nor want to pay several thousand to have someone do it for me.

So I'm trying to come up with other fixes.
