Looks fairly easy to install where I just took the old one out. But the old one has two wires coming into it, one black, one white. The instructions for the new one (hasn't arrived yet) shows three wires, with the third one attaching to a screw on the dishwasher's electrical box.
Since I only have two coming up from the house panel, can I just run a wire to something that should be grounded, maybe the drain pipe?
If it's BX, I wouldn't worry about it. The armor shield would act as a ground. If it's ungrounded Romex, you could run a seperate ground back to the panel ( not a pipe), or simply replace the existing breaker with a GFCI breaker which would provide protection in the abscence of a ground.
No, you need a proper ground, particularly with a device like a dishwasher. What kind of wire is currently servicing (or was servicing) the dishwasher? Unless it's pretty old, it should have a ground conductor, possibly the person who installed the previous dishwasher didn't connect the ground and cut the ground back for some reason.
Hmm. No, these are fuses. The wire is (having just looked up Romex and BX) BX. A white and black wire inside a metal snake-like housing. Then it sounds ok as is, with the metal sheath providing the grounding. That's how it was hooked up.
Apparently, as per the Mikepier post, I have a BX cable and that should be sufficient. That would make my life somewhat easier.
re: I have a BX cable and that should be sufficient...
=2E..assuming the BX is conected to a chassis ground at one end and an earth ground at the other. Simply sheathing the wires in a metal casing that is connected to nothing grounds nothing.
Just making sure we cover all bases here...
Thanks. I'll follow that cable and see where it goes. Clearly, it makes it to the fuse panel.
