Do generator interlock kits meet code?
They take next to no time to install, physically prevent the utility main being on at the same time as the generator breaker, and the inspectors seem happy with them (they meet code, so they better!)
Are Generator Interlock kits safe?
An interlock kit is a safe and cost-effective way to ensure you’re using a portable generator safely.
Do you need a special breaker for a generator interlock?
Your breaker needs to match the manufacturer of the panel that you are installing the Interlock Kit into. Look for a 2-pole 30 or 50 amp breaker for your generator breaker. Generally people use a 30 amp breaker, inlet box, and power cord for generators less than 10,000 running watts and 50 amp setup for larger units.
How do you use a interlock switch on a generator?
Quote from the video:
Quote from Youtube video: Once that's off you can slide your interlock plate upward as you can see here I'm going to push that up and now the breaker just below is your interlock. And I'm going to turn that breaker on.
Is generator interlock legal?
Generator interlock kits are legal in most parts of the US if they are approved by the UL under their standard UL 67. The interlock kits you install should have the UL listing otherwise they may be objected upon by electrical inspectors.
Can I use an interlock instead of a transfer switch?
Compared to a transfer switch, which is limited to a particular number of circuits, an interlock kit allows you to run power from a generator to any circuit within the electrical panel. While this is good in theory, there’s a risk of overloading the generator if it’s not sized according to the load.
How much does it cost to install an interlock switch?
You can get an interlock for as little as $20. And at the end of the day, you can install one for $800 or less. That includes the labor and the cost of buying items such as power boxes, breakers, and cords. If you have the money, buy a transfer switch.
How do you hook up a interlock generator?

Quote from Youtube video: Alright. So we're going to go ahead open the panel door we'll hold the bracket where it goes we'll show you how it works real quick then we'll go ahead and get a Philips screwdriver a number two
How does interlock switch work?
It acts as a manual version of the transfer switch by ensuring the main and generator breakers can’t be on at the same time. The interlock kit isolates those two systems. In one position, electricity from the generator can’t surge into the utility lines.
Where can interlock switches be found?
Manufacturing and industrial environments use interlock switches in machinery of all types. Interlock switches are also used in the domestic environment, in devices such as automated gates or slam-lock doors.
What is interlock switch?
In order to safely transfer the power source from a generator (and back to the main), a safety interlock is often employed. The interlock consists of one or more switches that prevent both main power and generator power from powering the dwelling simultaneously.
How many types of interlocks are there?
three types
There are three types of interlocks: – mechanical, – electrical, – logical.
What is pump interlock?
The All Purpose Pumps Water Supply Interlock shuts off water supply in the event of a high level warning and pump failure.
What is a breaker interlock?
A generator interlock kit (or just interlock kit) is a device designed to allow safe powering of a home by a portable generator during a power outage. It is a less-expensive alternative to purchasing and installing a dedicated transfer switch.
What is Backfeeding a breaker?
An electric panel is backfed when the main breaker is mounted in the cluster of breakers on the branch bus, instead of being separate, vertical, and above or below the branch-circuit breakers. It is essentially providing power “backwards” into the distribution bus.
What causes backfeed?
A common source of unintentional backfeeding is an electrical generator (typically a portable generator) that is improperly connected to a building electrical system.
What is reverse power flow?
> The flow of current back to the generator which is connected in parallel is called reverse power flow. > This may occur because of the failure of prime movers, at the time of paralleling and when generator is in off load.
