New homeowner finds out electrician didn't wire their home properly: 'Quite wrong and currently dangerous'

A homeowner asked for help on Reddit after their new house was not wired for a portable generator hookup as they had asked for.

The electrician only labeled a breaker "camper" and did not install an interlock. This caused a disconnect outside, but the outside box is marked "input only." Not only is the setup wrong, but it could be very dangerous. 

Here's what to know

The homeowner wrote: "Our house is almost complete and the electrical was finished up Friday. We were supposed to have it wired up to be able to hook up a portable generator. I noticed the electrician labeled the breaker 'camper' and there's no interlock switch. Main disconnect is outside. The box on the outside side says input only. I thought an interlock was required?"

That question drew a blunt response from commenters. 

One commenter said the setup was "Quite wrong and currently dangerous. The 'camper' breaker needs an interlock and needs to be in the main panel outside, not in the subpanel inside. (Unless you add a main breaker to the subpanel and interlock the camper breaker with that.)"

A generator inlet on its own is only part of a usable hookup. The critical safety piece is the device that keeps generator power and utility power from energizing the house at the same time. If that safeguard is missing, the installation can be dangerous while also leaving the homeowner stuck with a paid-for feature that is not actually ready to use.

More background

Portable generators can be a practical money-saver during outages when they are installed correctly. A proper hookup can help keep refrigerators running, preserve groceries, and avoid some of the unexpected costs that come with losing power.

A labeled breaker and an outdoor inlet can look official, especially in a brand-new house, even when the key transfer mechanism is missing.

But because the main disconnect is outside in this setup, the protection has to be arranged with that layout in mind.

There are two possible fixes: Either the homeowner could move the generator input and interlock it to the outdoor main panel, or they could add a main breaker to the indoor subpanel and interlock the "camper" breaker with it. 

The overall important takeaway is that the homeowner should not try to plug their generator into the input until it's corrected by an electrician.
