I think I know this one but I want to verify. Does a garbage disposal have to have a grounded outlet? How bout the furnace?

I have never seen a disposal or a furnace that did not require an equipment grounding conductor. However, the need for an equipment ground is really determined by the appliance. If the appliance has a three pronged plug (NEMA 5-15 or 5-20), then it clearly needs an equipment ground. For a hard wired appliance, like a furnace, you have to read the equipment specs. Appliance grounding requirements are governed by UL requirements.

Cheryl. i’ve installed about 384 garbage disposals (give or take) and every one had a green ground screw inside the wireing pannel plate under the motor. but that only goes for what i’ve installed, ie; Whirlaway, G.E. and Badger. i’d assume it applies to all, but i can’t say for 100% sure. icon_cool.gif
