Connections for a Dryer to a Generator
Electrical Question: I would like to connect a dryer with a 3-prong connection to a generator with a 4-prong connection.
The generator manual states that neutral wire and ground wire may be combined at load end. What is the load end? Does this sound correct to you?
This electrical question came from: Dave, a Homeowner from Kansas City, MO.
Electrical Question #2:
Is there a adapter for a 3 prong dryer cord to a 4 prong 220v 30amp generator cord?
This electrical wiring question came from Stephen , a Handyman in Carmel, New York.
Thank you for your electrical questions.
Electrical Answer:
3-Wire and 4-Wire Connections for a Dryer to a Generator
Application: Generator Cord Connections.
Skill Level: Intermediate to Advanced – Not recommended for Homeowners, best installed by a Licensed Electrical Contractor.
Tools Required: Electricians pouch of hand tools and Voltage Tester.
Estimated Time: Depends on the type and size of the generator output, the specific receptacle, and the available access to the project area.
Note: Generator power should always be wired through an approved transfer switch or circuit interlock device. Any part of the home electrical system must NEVER be back-fed using a cheater cord. Back-feeding is extremely hazardous for the home, the occupants and the electric utility company repairmen.
Important: Installing a generator and transfer switch must be well thought out and performed with a permit with all work being inspected.
Generator Power for an Electric Dryer
- Dave, the Load is what is connected to the generator or any power supply. Load is measured or described by volts, amps or watts.
- In order to safely connect and run an electric clothes dryer to a generator the generator must be sized large enough to provide the required 30 amps 240 volts which is the typical load of an electric clothes dryer.
- It is common that the ground and the neutral are bonded at the generator power source unless otherwise specified by the manufacturer or application specific wiring requirements.
Selecting a Generator
- All generators are not created the same, so it is best to consult the dealer or generator specifications to make sure it will provide adequate power for any connected loads that you wish to operate while on generator power.

Connecting a Dryer to a Generator
I buy used clothes dryers and sometimes they are not hooked up or nowhere near a 220 volt outlet. I know there are generators that can power a dryer but I cannot find any generator to dryer cable adapters. Do I need to make an adapter? I an looking for a “generator outlet to female 3-prong dryer plug” and “generator outlet to female 4-prong dryer plug” to test various dryers. Hope you can offer some information! Thanks.
Generator Dryer Outlet Setup
Hi Matt,
Consider making a small 30amp 240 volt 4 circuit panel, that plugs into the generator. From the panel wire out two circuits, one could be for a 3wire 240volt dryer outlet, and the other a 4wire 240volt dryer outlet. This setup could be mounted onto a piece of plywood which could be mounted near the generator.
Alternatively, if you will always be testing only one dryer, then you may consider a setup with the cord and plug for the generator connected to two outlet boxes, one 3wire 240volt dryer outlet, and the other 4wire 240volt dryer outlet. You could use two 4 square deep metal boxes that are connected together, side by side, and install metal industrial covers onto each outlet.
I hope this helps,
Dave
