240V 3-wire drier ground/neutral confusion

[shelly_belly]

Look in your main panel. Neutral and ground are bonded together. Any where were you had connected something to neutral you have also connected to ground.

Is this the reason I get shocked whenever I touch the metal on my coffee pot and the sink at the same time?

That is likely an ungrounded receptacle or improperly bonded water system. Maybe a short in the appliance.

Yes. The house was built in 1963. I can trace the receptacle ground back to the service panel and it has a grounding rod. How should the water pipes be bonded? Should they have their own grounding rod?

Thanks!

Assuming metal water piping, the water line as soon as it enters the house should be bonded to the ground bar in the main panel. The water meter should be jumpered and hot and cold lines at the water heater should should be jumpered...to maintain bonding in case of dielectric unions.

Check that coffee maker. Without a grounded outlet, the metal case could be hot.

Ha! Coffee maker has no ground. It only has a 2 prong plug.

Scrap it. You are playing you bet your life with it.

The power line is faulted to the coffee maker's case. It should be isolated from the case.

Probably good advice. And get some gfci's for your kitchen.

Walker,

Very well said and right on the money. Due to the fact that the line is terminated in a dedicated outlet, it IS according to code.

To the OP,

The GE Spa Panel from HomeDepot can be wired this way:

And it will fit the need very well.

Also: If wanted, a 4 prong dryer outlet can be installed directly in the Spa panel for the brewery panel if you want - like this:

Hope this helps.

P-J,

In this spa panel, it looks like there's room for another breaker above the existing breaker.

Is is possible to install a 120V GFCI breaker in there as well, to provide protect power for pumps?

Yes, that can be done. Please keep in mind that you would also have to provide another outlet (120V) for the pumps. The other possibility is to run the 240V/120V power from the illustrated Spa Panel outlet to your controller box and split out the 120V circuits within the controller. (Protecting them with breakers or fuses within your controller)

Hope this helps.

Sometimes the buss is clipped. Pull the breaker out and make sure there is a stab to plug onto on the third slot.

Not a problem with the GE panel fromh HD.

That's a nice option. I dont think CH or Homeline has that.
