does the amperage name plate on a three phase generator for the total, or for each phase?

Answer 1

The amperage ratings are per phase. Most generators are rated in kW or kVA. For example a 250 kVA generator rated at 480 V 3Ø could handle the following:

250 kVA ÷ 0.48 kV ÷ √3 = 300 amps.

This means each phase can handle 300 amperes.

Answer 2

Although 3 phase, the amperage on the name plate of genset is always for each phase, meaning the full load ampere that the generator can handle per phase...theres no such thing as total when you speak of 3 phase. Three phase has 3 wires that transmit power (current) so the rating is always based on the full load current per wire (per phase) that the genset can give with out over loading.

There are also rating that indicate as total 3 phase like:

Power in KVA or KW

Answer 3

The name plate of a generator normally is for its line current. For a wye connected generator, line current = phase current while in a delta connected unit, the phase current= Line current/1.732

Answer 4

Current is always for each phase. kW, kVA, Hp are total ratings for the motor.

Answer 5

kw is kilowatts. the out put of your generator .a load calculation on what you want to run,should be done,then size the generator to accomodate.+ 25% extra should do the job.

Answer 6

It's for the whole shooten' match. Capacities are never rated per phase because it's irrelevant.
