Can a transfer switch backfeed?

A transfer switch is required by the NEC for any connection of power to a home. An automatic transfer switch isolates your home from the power lines. This prevents back-feed, which occurs when the power goes back down the utility lines. Backfeed can not only damage the generator but has the potential to cause fires.

Does a portable generator need a transfer switch?

How does a manual transfer switch work?

This means any appliance on that circuit will be powered. Many manual transfer switches are NEMA rated for indoor or outdoor installation.

Do you need a GFCI switch for a portable generator?

Most built-in GFCI’s found on portable generators protect the household type 15/20A, 120-volt outlets, and not on the 120/240 outlets that are used to connect to home transfer switches. The only time you’ll need a GFI transfer switch to connect the generator to your home, is if your generator is fully GFCI protected.

This style of switched neutral transfer switch is also recommended for safe use with any generator that has a bonded neutral. At WINCO we offer 30 amp and 60 amp 3-pole transfer switches by Reliance Controls made specifically for GFCI protected and bonded neutral generators. Also designed for any installation requiring a separately-derived system.

How does a GFCI trip the main circuit breaker?

A small amount of current is induced in this loop by the running generator. and since the neutral wire passes through the ground fault sensor, the GFCI senses this induced current and trips the main circuit breaker in the generator.

How do I remove a loop from a transfer switch?

The easiest solution is to lift the ground wire coming from the generator inside the transfer switch, and secure it with a wire nut, by itself. This eliminates the loop. Your other choice is to install a Switched Neutral Kit (SNK) accessory with your transfer switch, available thru our website.
