Er...what 3 phase power circuit to install?
(OP)
Hi, the company I work for needs to use some machinery in the US, it says it requires 208v 3 phase, I think it requires 32amps ( >40 max ). Should I specify that a 40A circuit is required? The building already has 3phase to it.
Also, does the three phase give me 3 'normal' circuits to play with (110v) to power an ancilliary device that hangs off the power supply? I also need to get an ELCB and another circuit breaker for the machine, but am not sure of the spec...can anyone help? ? ? ?!

RE: Er...what 3 phase power circuit to install?
To answer your question about 110V power to "play with": 208 is the line to line voltage and 120 will be the line to neutral voltage. Most 3 phase 208 V loads require no neutral connetion, so your stuck with 208. I would reccommend powering the auxillary equipment from a seperate circuit. In any case....I believe you need some help from someone with an electrical background.
