Unusual Transfer Switch for Generator

Pic one is plug for generator and pic two is of two 30 Amps receptacles. The one on the left feed the subpanel from the main distribution panel, the one on the left is fed by the generator.

When power goes out one switch the plug from the distribution panel (left side) to the one fed by the generator (right side) and plug the generator.

Even though it is unusual, it appears to be safe. What are your thoughts?

What prevents the power feeding out to the grid? Are the male prongs hot coming out of the panel?

Transfer equipment even if manual is required to be listed. Is this safe, you would need to provide more information to make that determination.

You have to unplug the feed (left side in pic 2) of the sub panel from the main distribution panel (grid) and plug it in the generator feed receptacle (right side in pic 2).
The male prongs coming out of the subpanel are not hot as they are the feed to the subpanel.

This situation is unusual as stated.

The receptacles are listed, the plug is listed, the exterior switch is listed, the wiring is listed,…

Nothing become live when switched.

How is the plug hanging out of the panel is connected to the panel? If it’s from a back-fed circuit breaker then the prongs of the plug could be energized if the CB is on.

That was my thought too.

Marcel, is there an interlock on the panel breakers?

Pic 1 or pic 2?

In picture 2 the cord end would be live if the back feed breaker is on.

Two receptacles. The one on the left side (pic 2) is fed by the main distribution panel (not visible see attached pic), the other on the right side is fed by the generator (pic 1).[/FONT]
The plug is feeding the subpanel which provide power to the emergency circuits in the event of a power failure.[/FONT]
That plug feeding the sub panel is by one or the other (utility or generator) which appears to be safe.


It may appear to be safe but no ground is provided when transferring power to the generator…unless the generator is grounded.
