How do I convert this 220v outlet
|

| poison_1024@yahoo.com 2007-02-27, 1:26 pm |
| I have a device that requires a 220v 20amp outlet. The male plug on
this is like:
- |
o
I have a 220v 40amp recepticle on the wall which is like:
u
| o |
_
|
On the plug I assume the two prongs are both hots and the round prong
is the saftey ground with no neutral on the plug.
On my recepticle are the two straight slots the hots, the u the saftey
ground and the upside down L the neutral?
I can't remove this outlet and my concern is to not mix up the ground
and the neutral.
I'm not going to replace the outlet. I just want to make a little
extension cord adapter.

You sure that's 40A? Looks like a 30A configuration to me...
Go to this page
http://frentzandsons.com/Hardware%2...leconfiguratio.
htm
and verify that what you have is a NEMA 6-20P plug and a NEMA 14-30R
receptacle.
IF that's the case, then...

... correct

Sounds good to me -- assuming that you have what I think you have.

You might be right, I thought it was hooked up to two 20 amp breakers
but maybe they are 15A breakers. Especially since I don't see any 40A
rated outlets on the site. Nice site (although I found the correct
url at: http://www.frentzandsons.com/Hardwa...sonsHdweRef.htm)

This is a common misconception. A 30A 240V circuit uses a single 30A
double-pole breaker (or two single-pole 30A breakers with the handles
tied together), not two 15A breakers.
