is an essential part of our lives. There is safety for yourself and family as
well as safety for your properties and there is nothing that has to be secured
as compared to your home. The breaker panel load center interlock kit which is
also known as the breaker lockout will allow you to connect your portable
generator to your electrical system in a secure way without having to
experience the risk of back feed to utility power. With the generator supplying
power to your home electrical system, it removes the need for running the
extension cords within your home which both expose fire as well as safety
problems. Our kits are designed in a way that should be installed by qualified
electricians and should always meet the standards of the National Electrical
Code as well as the National Fire Protection Code. These kids are under UL 67
listed by an independent lab to be used within the US. These are not approved
to be used in Canada.
kit offers safety when it comes to your home electrical units that you want to
protect from any electrical related hazards. Besides our interlock kits ca fit
most of the panel boards which include a full line of accessories that connect
your portable generator to your home’s power system.
The mechanism of the interlock kit
panel board consists of a distribution and protection unit for electricity
within your home. The power is supplied from the utility direct into the panel.
then from here, it is supplied across different branch circuit breakers and out
into the rest sections of your home. The interlock kit enables you to be able
to disconnect your panel from the utility supply and switch it over to the
generator that is being supplied through a new generator breaker. The interlock
kit accepts one among these supply systems to be operating at the same time so
as to prevent both power sources from being in connection at the same time.
without an interlock kit or transfer switch, there is a possibility that
someone might forget and open the main breaker which can result in a risk of
electrocution to the men in service, damage of the generator as well as fire
a single connection, it is safe to use anything within your home as all the
circuits within your home have been activated via the breaker within your
panel. besides it removes the danger of running unseen and dangerous extension
cords to different sections of your home as well as the need to plug and unplug
appliances as well as lights.
an interlock kit has been installed, it is fast and easy to switch power from
the utility to the generator whenever there is a power outage. And it will
easily return the utility power once it is back on by reversing the procedure
- Flip the main breaker to the OFF position
- Flip all the branch circuits to the OFF position
- Then slide the interlock plate up or down depending on
the type of kit you own
- Connect and start your generator
- Flip your generator breaker to the ON position
- Switch on all the essential circuits each one at a
time. Let the appliances start before moving to the next circuit.
that impose large loads such as the microwaves, water heaters, dryers, etc.
might not be able to run simultaneously. Besides the breakers do not consume
power unless something within the room that they supplier has been cut on
making it fine to have the breakers that supply all the bedrooms, washrooms,
etc. on in order to have the power available for lights and such as you want
them. It is better that you first check on what can be run with your generator
to prevent the overload problem.
case you are having gas, propane or oil you can run the furnace or boiler so as
to keep warm. But, in case you own an electric heater it might not run as most
generators offer below 10000 watts and this means it might lack enough power to
run it. That is also so the same when it comes to the central air system as
well. The interlock will work to handle any capacity of the generator even
though if it happens that you have a heat pump or you need to run your air
conditioning system, then you must consider buying a 12000-15000-watt
How can I free up some space for my back feed breaker?
back feed breaker is normally applied for the generator input connection to the
panel. In order to connect the back feed breaker as well as the interlock, you
need 2,3 or 4 free space. You can read this on your user guide regarding your
panel requirements for your kit so as to identify the number of free spaces
that are needed within your panel. In case you lack space in your panel you
will have to get one piggyback breaker for every space that you want to create.
The piggyback breakers are sometimes known as the half-height breakers due to
the fact that they are manufactured with double space within a space that one
breaker normally covers. But the problem is that they are just available in
only 15 and 20 Amps ratings. Remember that in case you remove a 15-amp breaker
from your panel, you should replace it with another 15 Amp piggyback breaker.
Besides you should have an extra 15 Amp piggyback breaker somewhere within your
panel that should be paired upon it. In case you are removing a 20 Amp breaker
then the same rule has to be applied. In case you want to pair a 15 Amp and a
20 Amp breaker, then you will have to get a 15/20 Amp piggyback breaker. If you
fail to free up the necessary spaces, then you will not be able to use this
Is it difficult to install the interlock kit?
kit is supplied with a complete installation guide. The kit comes with
backplate, double-stick pads, front slider plate, thread lock, drill bit, and
- Make sure that you disconnect the power from the panel
- Then mount the backing plate in a proper position on
the panel cover using double-stick pads
- Isolate the panel cover
- Search for branch breakers to free the needed amount
of space for the generator back feed breaker as well as the interlock kit
- Connect the generator back feed breaker
- Connect the retaining strap around the back feed
breaker and the label
- Now drill 3 or 4 holes via the panel cover by using
the backing plate as the guide
- Isolate the burrs and file away the spot of pants in
order to allow sufficient electrical ground contact
- Connect the front slider plate using the included
- Switch off the generator and the main breakers and
then re-connect the panel cover
- Test the interlock to see if it is operating as it
- Apply the thread lock upon the interlock screws
- Apply the labels
kits should be connected, tested, serviced and maintained by a professional
electrician. Never try to do it yourself as you might end up dead unless if you
have ever done it before and you are among the licensed electricians.
What appliances are included in a kit?
The kit consists of a specially designed backplate as well as the front plate
that is able to fit the breaker panel, binder screws, binder posts, drill bit,
install instructions, thread lock, labels for the main breaker, generator
breaker, danger, operating instructions, retaining trap label and the retaining
strap. Because of different varieties of breakers that are available on market,
the kit does not consist of a branch breaker which is used as the generator
back feed breaker. You will have to purchase it independently in your local store.
Besides the outdoor inlet box, the generator code set and the building wire
should be purchased separately.
Is it identical to the transfer switch?
interlock kits are the ideal alternative in case there is no room for
installing a separate transfer switch or transfer panel upon the wall next to
your breaker panel or on the exterior section of your home near the power
company meter. These kits are explained to UL 67 by an independent lab. But
these interlock kits need the following:
- Customization/modification of your load center breaker
- Additional branch beaker spaces
- Sufficient installation and operation check
compared to many types of breakers which are factory built transfer switches,
the interlock kits do not operate when the front panel is not installed.
to prevent generator overloading?
Using these interlock kits in providing power to your
entire breaker panel might lead to overloading your generator. The damage
to the generator as well as some other appliance loads might originate from
these overloads. To prevent these possibilities, we do recommend that you
should install meters upon your generator feed to the panel. this will inform
you how much load is in use at any given time and how much spare capacity is
available for connecting additional loads. by having such information, you are
able to know which branch circuits within your breaker panel should be turned
on. You can purchase the generator meters from your local store or you can
visit our store as we have a wide option of generator meters.
to I know when the utility power is restored?
When there is a power outage, while the generator is
running your panel, the main breaker will be in an OFF position. Therefore it
will be hard for you to identify when the utility power has been restored
unless you notice that your neighbor’s lights are ON. But we have an easy
solution for this which is a power back appliance that will alert you when the
utility power is back.
Just make us a call or visit our office as we will be
happy to offer you help. You will be able to go through our different options
of electric appliances that will help in making your home or office safer than
it has ever been.
