Product FAQ | locking rate (2023)

The interlock kit is a device that creates mechanical interference between the main breaker and the generator feedback breaker. This interference prevents both switches from being turned on at the same time. By "interlocking" these switches, you will have protected the utility system, ensuring that your generator does not accidentally connect power to the grid while it is running.

Using our Kit improves the security of your home or business while using a generator. No need to run multiple extension cords to different outlets. With the lockout kit, you can simply plug one end of the generator power cord into your generator and the other end into a generator convenience inlet box or receptacle plug.Forget expensive circuit breakers that limit your accessibility, and run it all with the ORIGINAL interlock kit instead.Depending on the capacity of the generator, it can power all of your home's circuits.

Interlock kits must be installed by qualified electricians. We use MET Laboratories, one of America's most trusted laboratories, to test our interlock kits in accordance with UL 67 and the National Electrical Code.

Care must be taken to select the correct interlock kit! We use the following ways to combine interlock kits:

• First determine who the manufacturer is
• Then notice where the main switch is located on the dash. is it centered? Is it offset to the right or left of the center of the panel? Is the main circuit breaker connected to branch circuits? Is it located above the branch circuits? How many amps is the main switch?
• If there is a gap between the main breaker and the branch circuits, measure the gap. Starting at the bottom of the main breaker, measure to the top of the branch circuits. (inches)
• Finally, determine the launch direction of the main switch. It's the main release; horizontally (left to right) or vertically (top and bottom)?

After reading the following, go to the "Interlock Kit Selection List" on our website. If you don't see the selection list, click on the drop-down menu located in the upper left corner of the screen. This menu will list the manufacturers that each kit is compatible with. After selecting your manufacturer, you will see several dashboard images displayed. Following the steps above, select the interlock kit that most closely matches the description of your own panels. If you would like confirmation from one of our interlock kit experts, simply send a photo of your electrical panel to: question@interlockkit.com or call (804)726-2448

An electrical switchboard is a distribution and protection system for electricity in your home. Power is fed from the utility to your panel. From here you go through the different breakers and then out to the rest of your house. Our product, the original interlock kit, will allow only ONE of these power systems to be operational within the panel at any one time. This avoids dangerous feedback scenarios.

When transferring from one power source to another, follow these steps:

• Turn the main circuit breaker to the "OFF" position
• Turn the BRANCH circuits to the "OFF" position as well
• Slide the interlock kit: up, down, left or right at this point to lock the main switch in the "OFF" position.
• Plug in and start your generator
• Turn the GENERATOR breaker to the "ON" position
• Turn on your essential circuits one at a time!

*Warning: Let your appliances start working before connecting the following circuit breaker*

To transfer back to mains, reverse these steps beginning with turning the GENERATOR breaker to the "OFF" position.

Note: Not all large loads, such as water heaters, microwaves, dryers, etc., can run at the same time. Remember that the switches themselves don't draw power unless something in the room they turn on has been turned on. For this reason, you can turn on all your light control switches while moving around the house, you can turn on the lights as you walk, but don't forget to turn off devices that are not currently in use. If you have electric heat or central air conditioning, most generators below 10,000 watts will not have enough capacity to run these items. Lockout kits are compatible with generators of any size, we recommend something as large as 12,000 or 15,000 watts to run your AC unit. This does not apply to homes with gas, oil, or propane heating.

Typical appliance power

• Electric water heater – 4500 watts
• Microondas – 1600 watts
• Toaster – 1800 watts
• Stove top element (one) - 2200 watts
• Hairdryer – 1500 watts
• Well Pump - 2000 Watts
• Bilge sump pump - 900 Watts
• Geladeira – 700 watts
• Freezer – 700 watts
• Oven or boiler – 700 watts

Even with just a 6,000-watt generator, you can do almost anything in your home that you normally would, just not all at once. (depending on the capacity of your generator)

Most appliances have the wattage clearly indicated, if not; if only amps and volts are given, just multiply them to get watts. (10.2 amps x 120 volts = 1224 watts)

A licensed electrician would use non-metallic wire (Nm wire commonly known as ROMEX) and connect the generator breaker to the outlet box or convenience receptacle.

After moving your interlock kit to lock out the main breaker, simply plug one end of the generator power cord into the generator and the other end into the receptacle in the headbox.

Rear power switches (generator switch)

Your breaker must match the manufacturer of the panel in which you are installing the interlock kit. Look for a 2 pole 30 or 50 amp breaker for the generator breaker.

Generally, people use a 30 amp breaker, input box and power cord for generators with less than 10,000 running watts and a 50 amp setting for larger units. For generators with outputs greater than 50 amps, consult factory.

*See photo below for an example of a two-pole feedback circuit breaker*

Piggyback or tandem circuit breakers

These switches allow you to create space. most switches have a single toggle switch. In the case of the tandem switch, two independent switches will be consolidated into a single switch space. This allows you to create an open space by combining two switches into one space.
