Quick Answer
A typical generator remote start kit requires a 10-20 amp circuit to operate, depending on the specific kit and the generator's power requirements. This usually translates to a 12-gauge wire or smaller. It's essential to consult the remote start kit's documentation and the generator's manual for specific wiring recommendations.
Choosing the Right Wire Gauge
When selecting a wire gauge for a generator remote start circuit, consider the ampacity requirements. As a general rule, a 10-20 amp circuit can use a 12-gauge wire. However, if the circuit will be longer than 50 feet or will carry more current, consider using a 10-gauge wire for added safety. For example, a 10-gauge wire can handle up to 30 amps of current, making it suitable for longer or more demanding circuits.
Determining Generator Power Requirements
To determine the required ampacity for the remote start circuit, consult the generator’s manual or the remote start kit’s documentation. Typically, a 5-kilowatt generator requires a 15-20 amp circuit to operate. However, if the generator has a higher power rating or will be used with additional loads, consider increasing the circuit ampacity accordingly. For example, a 10-kilowatt generator may require a 25-30 amp circuit to operate safely.
Installation Considerations
When installing a generator remote start circuit, ensure that the wire gauge and ampacity meet the generator’s requirements. Also, consider the circuit’s total voltage drop and the remote start switch’s current draw. A voltage drop of 3% or less is usually acceptable. Additionally, ensure that the circuit is properly grounded and that all connections are secure to prevent electrical shock or fire hazards.
