dryer

[Dusty MI]

Anyone know what the NEMA # is for the 3 wire 230 volt 30 amp receptacle for a clothes dryer ?
I know a new installation needs to be 4 wire but I have to go and replace an old one.

Thanks,
Dusty

Nema# 10-30R three wire.

This would be he te to upgrade to a proper 4 prong system.
How difficult could it be to find a water pipe in a laundry room
that runs out through the wall underground. Or run a ground
wire to the electrical service ground or a well casing.
14-30 plug and receptacle.
Why Mickey Mouse something electrical around water
where people walk around in bare or stocking feet?

Hey there Dusty, Okay you stated 30 amp,,,,,, 3 wire,,,,,,,,Clothes Dryer,,,,and,,,,,,Receptacle

According to a NEMA Chart that would be a NEMA 10-30R Receptacle which is same as you asked, a 125/250 volt, 3 Pole 3 Wire, 30 Amp Receptacle

The modern dryer configuration that has BOTH 120 and 240 volt 30 amp circuitry calls for a NEMA 14-30 which is a 3 Pole 4 Wire Grounding.

Dusty,
Two years ago I added on to the house, put in a new bath and laundry room upstairs. Used 10-3 w/ground. Everything was approved by the building inspector. New dryer from lowes. Free delivery and they put a 4 wire cord on the dryer.

Here is the crazy part. Guess where the ground and neutral wire was connected on the new dryer? One would thunk there would be two seperate places to isolate ground and neutral at the dryer. Guess again. So much for doing things by the new 4 wire code. You would think Whirlpool would have changed the wiring of the dryer, but they didn't.

Sometimes I wonder about the people making building codes. This should stir the pot a litte, don't you think John T?

Based on yearsssssssssss of experience, Id say "local government officials" arent the sharpest tool in the box lol. However, when it comes to the panel of true experienced professional experts who author like the National Electrical Code, Underwriters Laboratory, Plumbing Codes and HVAC etc. NOW THOSE GENTS ARE GENERALLY RIGHT ON

JohnT, Next time you are Lowes or any appliance store, take a look see at the new 4 wire dryers. Report back on what you find. Have a good day.

The dryer will have a bonding strap installed between the
neutral and the frame. You leave it in place for a three wire
system and remove it and install the ground to the frame for
a four wire system. Been this way for decades since the
ground was required for mobile homes long before the code
changed to require it for all installations. Lowes takes a big
liability by having unqualified installers.
