Hey everyone. I'm having trouble figuring out if it's possible to run a dishwasher and washer/dryer combo off of one switch? Switching back and forth so not one is just on consistently

What are the power requirements for each ? Manufacturer name and model number ?


Regards, Dana.

What are the equipment power consumption ratings?

The total consumption (amperage) should be LESS than the switch rating PLUS the circuit wiring (to the outlet) should be capable of taking the load.

Both rated for 120v. Still not sure on make and model management is behind on ordering them.

Not the voltage - the wattage ( or the amperage).

A typical washing machine may, when heating water, consume 2kW (or more). A dryer can run to 3kW. Add in a dish washer may be around 1.5kW. Total for BOTH operating would be 4.5kW and, with allowance for 'extras' round up to 5kW. 5kW at 120V is over 40amps..... a 50A or 63A switch would be needed and the cable feeding the switch/socket suitably rated as well as the main MCB in the distribution board.

How are the devices to be attached to the power supply. They normally come with plugs attached so two socket will be required. If they are just hard wired into a single switch (not a good idea) then that switch will need to have the ability to safely take two cables - no switches that I know of have this capability.

It is possible to run a dishwasher and a washer/dryer combo off of one switch, but it will require some wiring and electrical work. Here are the steps you would need to follow:
  1. 1. Determine the electrical requirements of the appliances you want to run off of the switch. You will need to know the voltage and amperage ratings of each appliance, as well as the type of outlet they require.

  2. 2. Choose a switch that is capable of handling the electrical load of the appliances. The switch should be rated for at least the total amperage of the appliances, and it should be able to handle the voltage of the outlets.

  3. 3. Wire the switch into the electrical circuit that supplies power to the appliances. This will typically require running new wires from the switch to the outlets for the appliances.

  4. 4. Install the switch in a convenient location, such as on the wall near the appliances. Make sure the switch is properly grounded and connected to the electrical circuit.

  5. 5. Test the switch to make sure it is working properly and can turn the appliances on and off as needed.
It's important to note that this type of electrical work can be dangerous and should only be done by a qualified electrician or someone with the necessary knowledge and experience. If you are not comfortable working with electricity, it is best to hire a professional to install the switch for you.
