480 receptacle

[normbac]

does it matter what phase is on x y or z on a receptacle its a 480 v TIA

Depends on what will be plugged into it, and it might depend on how other 480 volt circuits from the same source are wired. If this is for a motor, then selecting the wrong pattern will cause the motor to run backwards.

As Charlie said, other than motor directions it doesn't matter. Although with a lot of portable equiptment with different wiring approaches it may be possible to unbalance a system, but trying to prevent that is near impossible. :roll:

I usually just put BOY on 123 or xyz depending on how the terms are marked and just bump the motor to check rotation and if its spinning backwards switch 2 of the leads.

Lets say you are actually hooking this receptacle up, you never mentioned if
you had a 3 phase 480 power supply or 1 phase 480 supply.......

If he's got single phase, and has X Y and Z on the recep, he's got the wrong recep.

That's right , and same would apply if he said 208 volts.

I was sure he meant 483 phase.:grin:

XYZ does not really matter it could be WHL what matters is rotation if you are going to have a motor load.
