Dishwasher electrical question


How high in the wall behind the dishwasher do i install a box for a recepticle for a dishwasher. I am going to use Cab wire and have it plug in instead of hard wired. Looking at the dishwasher manual is shows all electrical needs to be with in 6" from the floor. Can anybody tell me for sure the correct way for this so i can pass my rough in. I am in Alberta.

Thanks

I did'nt think you could have a plug in do to water issues and if you had a plug it would have to be a protected circuit which i would think might cause tripping problems

I'm not sure what "Cab wire" is or specific rules for Canada
In the US it can be setup as a plug-in, cord can only be 5' (?) long
We do have some people who know codes on Canada
Hopefully they can help you

Yes here its also 5', most new installs are plug in for ease of service, and cab wire is what the electrician i talked to said to use but cant get ahold him again.

Dishwasher electrical question


Cab tire is another name for SJOW, SOW, etc.

I can't answer your location question, if it was me I would hard wire it. Its not like your pulling it out every week to do maintaince on it. I have lived in my house for 6 yrs and I have never had to take the dishwasher out or turn the power off to it.

Your best bet would be to call the inspector and ask what he wants to see, that way you know it is done right.

Cabtire cable is/was made up of stranded wire, with rubber insulation and a rubber sheath, originally!
Plastic insulation and sheath are now used extensively!

I have always plugged dish washers in, rather than hard-wire them, as its usually a nasty job to make the connection with the washer in position.
The main thing is to place the outet in such a position, that it isn't interfered by washer frame.
I have always used a 'Handy Box' mounted about an inch above the floor to ensure that there is clearance!

Dishwasher electrical question


This is how the 2008 NEC reads at 422.16(B)(2)
(2) Built-in Dishwashers and Trash Compactors.
Built-in dishwashers and trash compactors shall be permitted
to be cord-and-plug-connected with a flexible cord
identified as suitable for the purpose in the installation instructions
of the appliance manufacturer where all of the
following conditions are met:
(1) The flexible cord shall be terminated with a groundingtype
attachment plug.
Exception: A listed dishwasher or trash compactor distinctly
marked to identify it as protected by a system of
double insulation, or its equivalent, shall not be required to
be terminated with a grounding-type attachment plug.
(2) The length of the cord shall be 0.9 m to 1.2 m (3 ft to
4 ft) measured from the face of the attachment plug to
the plane of the rear of the appliance.
(3) Receptacles shall be located to avoid physical damage
to the flexible cord.
(4) The receptacle shall be located in the space occupied
by the appliance or adjacent thereto.
(5) The receptacle shall be accessible.

# 5 can still be behind the DW thats why #2 reads the way it does.
NO height is given. The length of the cord is so you can pull the appliance out to unplug it. So it cannot be extremly high. Check with your local inspector.
