7+ Tips For Hooking Up Your Portable Generator
Hooking up a portable generator in your home requires you to have a transfer switch that is suitable for disconnecting your electric loads from the utility grid of your electric power supplier for your house. For hook up of home single phase 120 or 240 volts of power you'll need a double throw and double pole type.
Double throw means that you can move the switch into two positions. One of these positions feeds the power to the load from your house utility system. The other feeds the power to the load from the portable generator.
Hooking up a three phase portable generator would require you to have a double throw switch that is three poled. This means that you'll have added a lever for manual switching that is extended, so that you can turn the switch on or off from the ground.
If you're hooking up a portable generator at your home that is small and only used to run a few things such as a well pump, or a single large appliance that will be plugged directly into your house's generator, you won't need a transfer switch. It's just when your portable generator has to have a hook into your wiring at your home that you'll need the transfer switch. Put your home transfer switch between the loads you need to serve and your utility meter no farther than 25 feet from the generator.
If you're hooking up a portable generator that is driven by an engine and has an automatic start up you'll generally find the transfer switch already built into the generator's automatic controls. Make sure you ground the portable generator as you hook it up in your home. Use solid wire made of copper and a ground rod that is 8 foot.
