Dishwasher Cord


Can I use this cord: HOME DEPOT for Dishwasher?

Can't seem to find anything specifically listed for DW except one that is less than 6', and that won't do.

Circuit is 20a to 15a receptacle under the sink. The one linked above is rated for 13a, don't know the rating on the DW.

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

Oh, OK! Well, this project will be fun then.

There's only about 4" of Romex entering under the cabinet for the GD, and so I'm installing two duplexes close to that entry, and that makes the DW cord actually needing a bit more than 6'.

Install a jbox under the sink in addition to 2 receptacles for DW+GD?

Wait a min. Jim, is this saying that the cord can be only 4' MAX? Maybe I'm not understanding some of the language: measured from the face of the attachment plug to the plane of the rear of the appliance.

What's with this?

What the nameplate rating on both dishwashwer et garbage dispoal unit ?

Techallywise if the ampacity is not over 50% of what the circuit is rated for so like example on 15 amp circuit it can not be over 7.5 amps or 10 amp on 20 amp circuit.

Merci,
Marc

Depending on amps both pull at one time they should both be on dedicated circuits.NEC

No, that's not what it is saying.... you can use a 6' cord.

4' from the plug to the rear of the DW. The cord can be long enough from there to reach the JB on the DW which is usually at the lower front. About 2' from the rear of the DW to the front,so a 6' cord is fine.

Marc, you left out the part that with the Dishwasher & Garbage disposal, the two of them cannot exceed the max breaker rating of 20 amps, and the 80% does not come into play in this type of setup.

Some areas now require disposalls and dish washers to be on their own 15 amp or 20 amp circuit, but some others, still allow both to be on the same 20 amp circuit, as long as the total of the amps of those two appliances do not exceed the max rating of the breaker.

That section you posted does not apply in this setup.

I don't believe it applies here:

This is not the case. No lighting is supplied, nor is any cord and plug non-fastened in place equipment.

(2) Utilization Equipment Fastened in Place. The total rating of utilization equipment fastened in place, other than luminaires, shall not exceed 50 percent of the branch-circuit ampere rating where lighting units, cord-and-plug-connected utilization equipment not fastened in place, or both, are also supplied.
If all equipment on the circuit is fastened in place the 50% rule does not apply.
