Large, fixed generators generally are directly connected to building wiring to provide standby power during emergencies and power outages. However, the wiring needs to be properly installed by a qualified electrical contractor. Properly installing a “permanent” generator is extremely dangerous, and not a “do it yourself” job. If you plan to have this type of generator installed, you may need to obtain an electrical permit from the Building Department. For more information, please call 860-665-8580.

Back Feeding

“Back Feeding” is a dangerous condition. Improperly connecting a portable generator to electric wiring can produce “back feed” - a dangerous current that can electrocute or critically injure you or others. Back feed into power lines from a generator could create “hot” power lines during an outage. Linemen who expect the line to be de-energized could be injured. One good way to avoid back feeding is to install a double-pole, double-throw transfer-switch gear. A qualified electrical contractor can install this transfer switch so that a dangerous back feed can be prevented. The switch also will prevent utility power from damaging the generator when regular service is restored.
