This hole will allow you to pass the wires from the power inlet box into your breaker box. Make sure to choose a suitable location that is easily accessible and won’t interfere with any existing structures or utilities.

Mounting Power Inlet Box

Once you have drilled the access hole, it’s time to mount the power inlet box on the exterior of your home. The power inlet box should be located near the access hole for easy connection of the generator. Use screws and anchors to secure it firmly in place.

Wiring the Generator Inlet Plug

Now that the power inlet box is mounted, you can proceed with wiring the generator inlet plug. Follow the manufacturer’s instructions carefully and ensure that all connections are secure. It’s crucial to use proper wire gauges and connectors for safety reasons.

Preparing Breaker Box for Wires

Next, prepare your breaker box for connecting the wires from the generator. Ensure that all breakers are turned off before working inside the breaker box. Remove any knockout tabs or covers necessary to accommodate the incoming wires.

Installing Generator Breaker and Wires

With your breaker box prepared, it’s time to install the generator breaker and connect it to your home’s electrical system. Carefully follow all instructions provided by both your generator manufacturer and automatic changeover switch manufacturer. Make sure each wire is connected securely according to its designated terminal.

Operating the Connected Generator

Once all the wiring is complete, it’s time to test your setup and operate the connected generator. Ensure that your automatic changeover switch is in the correct position for generator power. Start up your generator following its specific instructions, and verify that power is being supplied to your home through the breaker box.

Connecting a 1-P & 3-P Portable Generator to the Home Supply

Required Supplies for Wiring

To connect your portable generator to your home supply, you’ll need a few essential supplies. First and foremost, you’ll require a power inlet box that acts as the interface between your generator and your home’s electrical system. You’ll need an appropriate wire gauge, depending on the power requirements of your generator. Don’t forget to have wire connectors, electrical tape, and wire strippers on hand to ensure proper connections.

Drilling Access Hole for Wiring Installation

Once you have gathered all the necessary supplies, it’s time to drill an access hole for the wiring installation. Locate a suitable spot near your breaker box where you can easily route the wires from the power inlet box. Use a drill with a hole saw attachment to create an appropriately sized hole in the wall.

Mounting Power Inlet Box

With the access hole in place, it’s time to mount the power inlet box on the exterior of your home. Choose a location that is easily accessible but protected from rain or other elements. Securely attach the power inlet box using screws or bolts provided with the unit.

Wiring the Generator Inlet Plug

Now comes the crucial step of wiring the generator inlet plug. Begin by carefully stripping off about half an inch of insulation from each wire end using wire strippers. Connect each wire securely to its corresponding terminal inside the power inlet box following manufacturer instructions. Ensure tight connections and use electrical tape or wire connectors for added safety.

Preparing Breaker Box for Wires

Next up is preparing your breaker box for connecting wires from both your main electrical supply and generator.
