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.
