Answer J:

The voltage that the phase converter will produce is based off the incoming

single phase voltage. The phase converter will use your voltage measured

leg to leg on single phase as a baseline for balancing the voltage. Leg to leg,

voltage may vary by about 5% while under load. The phase converter does

not transform the voltage up or down. If you need to raise of lower your

voltage, a transformer may need to be added. Please contact American

Rotary for assistance.

Answer K:

Do not measure line to ground. T3, the manufactured line references a

floating ground. The output of a phase converter is a Delta three phase

voltage. If a neutral or 120 volts to ground is needed from all three lines, a

Delta-Wye transformer is needed. American Rotary stocks the correct

transformers for this.

Answer L:

You may need bigger service. Everything may be big enough on your end,

but sometimes the power company's transformer is not big enough. Call your

power company for service.

Answer M:

Blowing a start capacitor is a result of too frequent starts or having a load on

when starting. Make sure all loads are disconnected when starting, including

transformers.

Answer N:

Check and tighten the bolts on the conduit box and all 4 through bolts on

both end bells.

Answer O:

Popping or blowing breakers might mean that there is a short from improper

wiring installation. There may also be grounding connected somewhere that

should not be. Check the phase converter and the idler for both of these

potential problems.

Answer P:

Your breaker may be undersized. Check sizing requirements for your current

setup. If further assistance is needed in sizing, contact American Rotary.
