20 amp plug
 

I'm installing a whirlpool tub on a dedicated 20 amp GFI circuit. I went to hardware expecting to buy a regular 2 plug outlet but I found a round single plug 20 amp 125 volt plug. It will take a normal plug but has an extra slot running perpendicular to one of the slots. Should I use this plug?

The one I was going to buy was 2 plug 15 amp

I probably would use a 20 double ( duplex) outlet. My thoughts are just in case you have to get under it to work on it that way you have a way of plugging in a light while keeping power to it for troubleshooting if needed.

What you describe is correct for a 120V/20A receptacle. It is also available in a duplex. But you MUST use a 20A receptacle. If it does not have the perpendicular(horizontal) slot, it is not a 20A receptacle and should not be used in a 20A circuit.

This is simply not true.

Oh no! Not this discussion again.

I think Bill is referring to a single receptacle. :yes:

We'll see...:whistling2:
