Frequently Asked Questions
What is a back-feed?
A back-feed occurs when electric power from a generator is fed from a home or business, back onto utility power lines. This occurs when generators are connected incorrectly or "jury-rigged" using a non-code-approved method.
What appliances can I run on a portable generator?
You should be able to operate most of your home's appliances, but not all simultaneously. It can't, however, handle the start up needs for heat pumps or central air conditioning systems.
Where should a portable generator be located when in use?
The generator should always be placed outdoors on a level, firm surface. Never operate a portable generator indoors, in a garage or any attached structure as carbon monoxide poisoning may occur. Always operate your generator away from open windows, doors and combustibles. Refer to your owner's manual for complete operating instructions. Is there any potential for damage to my appliances?
There is no risk of damage from any approved interconnection/transfer device. You should take care when selecting your generator to make sure you're buying a high quality generator.
What happens when utility power is restored? With the Connection Hub, you will automatically switch back to utility power once it's restored. Your generator will continue to run, so you will need to turn it off and unplug the power cord. With the Eight-Circuit Sub-Panel, the generator will remain your power source until you turn it off, unplug it, and flip the transfer breaker. What if I overload the generator? Your generator should have a circuit breaker that will activate in the event of an overload. If it doesn't have this feature, it isn't suitable for use with the Connection Hub.
What is an interconnection device? An interconnection device allows you to connect a portable generator to your home's electrical system, while simultaneously disconnecting you from the utility grid. This eliminates any chance of a dangerous back-feed. How can I tell what type of interconnection device I need? The type of device you need is based on two items: the generator size and/or the size of your electric service. The Connection Hub is applicable for service sizes of 200 amps and less, and generators up to 12,000 Watts. An Eight-Circuit Sub-Panel must be used for all services greater than 200 amps, regardless of the generator size. To determine the size of your service, check the main breaker size on your electric panel. As a rule of thumb, if you have one panel box, your service size is 200 amps or less. If you're still not sure, look for the service size indicator on the face of your electric meter (left side, middle).
