If we have a 220VAC L6-20 connection and we have a load of 2400W, then 2400W / 208V = 11.5 A.

Is that 5.75 amps per hot leg ? Or can it not be expressed that way.

Thanks for your help,

 

So if i read this right an L6-20 connection is just a mains connector with a live, a neutral and an earth.

How did 220VAC suddenly become 208V when you wanted to calculate the current?

If by hot leg you mean live/neutral then the full current passes through both pins I'm afraid.

 

We generally say 220V, but we really only get about 208V. I used 208V for a more accurate calculation, but it was not really necessary for this example.

A NEMA L6-20 has two hot legs and a ground ( X, Y, G ) . This is being used to power a large projector.

Thank you for your time and help.

 

220/230/240vac is the standard voltage between the two phases of the residential power supplied in the USA. 110/115/120VAC is taken from neutral to either phase. 208vac is the voltage taken between any two phases of a three phase Y-system, with 120vac from any phase to neutral.
