Domestic power here is 120-240 because it is just a split phase of a delta wired transformer. So the two are 180 degrees apart.
Commercial can be 120-208 or 277-480. They are always 60 degrees apart and usually are three phases of either wye or delta transformers.
Ahhh too advanced for me... Not get any more technical with this just give us a brief on why and its advantages pls
Volt/amps are watts...
Ye i know your triangle... ... Do u know ours??? No clues for u ur old enough and smart enough to work it out...
A famous mathematical triangle in engineering???
Best explanation is think of a garden hose.
How much pressure the water comes out with is the volts...
The amount of water in the hose is the amps.
the rate which the bucket which gets filled is watts.
Increase the volts but lower the amps but the buckets keep coming just as fast anyway. Same number of watts delivered.
Lower the volts but increase the amps and you are still delivering the same watts.
Ah, cool. Whenever i think about electricity i kind put on my pipe fitting gear and think about electricity like plumbing... Basic electrical
Breakers are sized for amps...volts too but a 20 amp breaker is pretty common.
@ 120 volts I can only get 16-17, 100 watt fixtures on one 20 Amp circuit.
@ 277 volts I can get over 30, 100 watt fixtures on one circuit.
Ye i think we have 10 and 15 for the single phase and 30 for 3 phase by memory.
Forget but i kept flipping them with welding machines over the years
