Electrical Wiring For A Dishwasher

Installing Electrical Wiring for a Dishwasher: Garbage Disposal and Dishwasher Wiring, The Process for Wiring a Dishwasher.

How to Wire a Dishwasher
Electrical Question: I have a wall switch that I will keep but I want to extend the wiring to a new under bench top switch to run our dishwasher. Can I do that by simply joining additional cable to the earth, power and neutral wires and extending them to the new switch?

Background: Jack, a Homeowner from Manningham, South Australia.
Additional Comments: First use but appears as if it could be very helpful.

Dave’s Reply:
Thanks for your electrical wiring question Jack.

Preparations for Wiring a Dishwasher

Skill Level: Intermediate to Advanced.
Tools Required: Basic Electricians Pouch Hand Tools, a flashlight and Voltage Tester.
Estimated Time: Depends on personal level experience and ability to work with tools.
Precaution: Identify the electric circuit, turn it OFF and Tag it with a Note before working with the wiring.
Advice: Be patient – working under the sink on dishwasher and disposal outlets can be very challenging due to cramped space and limited access. I find it very helpful to use a thick towel or throw rug as a cushion against the base of the sink cabinet.

The Process for Wiring a Dishwasher

It is best to have the dishwasher on a specific circuit that is allocated for a dishwasher.
Here in the USA the garbage disposal and the dishwasher may share the same 120 volt circuit.
Extending wiring from a wall switch to provide power for another appliance might not be possible because the wiring for a switch may not include all of the circuit conductors, and this would have to be verified.
Make sure you research what the circuit requirements are for the dishwasher you have and what is the approved method in Australia, and of course what the dishwasher installation manual specifies.
New NEC Codes are requiring ground fault protected circuits for these kitchen appliances.
