dishwasher pig tail


My dishwasher did not come with a plug, instructions says to run romex to it (hardwired) I have a receptacle under the sink.

Can I buy one of those 110V power cords with 3 prong plug and run that into the dishwasher instead?

BTW I am trying to find out the the drain hose size, is it 7/8"?

Thanks

According to the Code the cord must be listed for use with a DW. There are also length restrictions.

You should be able to get a cordset for the manufacturer of the DW.

You are right, I do find that they (Bosch) makes one, but it's very subtle because the installation instructions do not mention it.

Doesn't the dishwasher need a means of disconnect? Would a cord from the dishwasher plugged in under the sink satisfy the means of disconnect? Also would that outlet under the sink need to be GFI protected?

Don't see why you'd need a GFCI since it's not on the countertop, plus don't motors and GFCI not play well together? As for means of disconnect, I've seen plenty of DW that are hardwired (mine included) so I can't believe that's the code... then again... :-)

Yes, a cord and plug is a means of disconnect.


And no GFCI protection required.

This is simply untrue...

You need a means of disconnect, there are some rules that go along with it... but most likely your setup does not meet code.

I have seen many dishwashers hardwired also but they usually have a switch on the wall for the means of disconnect. Thanks for your knowledge Chris

The main thing is that the disconnect is within sight of the motor, so you have some choices.

A wall switch.

A unit switch on the dishwasher that actually disconnects the ungrounded conductors.

A Panel within sight of the dishwasher,

or a cord and plug on the unit itself.

this of course is only for motors that draw more than 1/8 HP.
