Question:

My machinery requires 240 3 phase. Can I get this without a transformer?

Location: USA - I get 120v on all 3 legs of 3 phase system but check 208v between any 2 legs. Can I step it up to 240v without a transformer? My machinery specifies 240v

Answer:

Most houses are supplied with only two of the three phases available in the USA. The circuit breaker box divides the two phases into two sets of 110 volts (each phase to ground) and also has circuit breakers for 220 volts (across the two phases) for clothes dryers and electric stoves, etc. Most factories are supplied with all three phases and certain motors can be connected (by licensed electricians) across all three phases to obtain 440 volts using a motor controller. Local codes and insurance requirements are two good reasons to hire a licensed electrician to safely connect the motor. A transformer may be required to obtain 220 volts and three phase current. Also check the name plate data to determine the required frequency (60 Hz) in the USA.
if your gadget is below 10 HP, it is switched on right away in delta configuration, no could connect the independent, yet while that's previous 10 hp it required to start in celebrity and then to alter to delta after commencing, then ask ability enterprise to connect independent.
Assuming you want 240 volts 3 phase ... No, you need a three phase transformer, or 3 single phases transformers. .
Most 240V. machinery will operate on 208V. (Check the 'spec.s., Ask the manufacturer.) If your equipment really does require '240V. actual', an electrician can set you up with a three single phase 'boost' auto transformer rig, for a whole lot cheaper then a standard transformer.
