Code and Insurance, at a Glance

A listed, approved interlock kit is a code-recognized way to connect a generator — unlike backfeeding, which is illegal and can't be permitted or inspected. Local code, plus a permit and inspection by a licensed electrician, confirms the install was done right, and the paperwork is worth keeping. An unpermitted or DIY hookup can complicate an insurance claim after a fire or injury, and can be a red flag when you sell your home. This is general information, not legal or insurance advice — rules vary, so always check your local building department and your own insurer. There's a printable 29-page version up top.

Common Questions

1 Is an interlock kit up to code?

A listed, approved interlock installed by a licensed electrician with a permit and inspection is generally a code-recognized way to connect a generator — unlike backfeeding, which isn't. What your area requires is set by your local building department, so confirm the specifics with them.

2 Will an interlock affect my home insurance?

In general, insurers expect work to be done properly, and a permitted, inspected, documented install is the kind of thing that helps rather than hurts. But every policy differs, so ask your own insurer directly — that's the only reliable answer.

3 What happens if I skip the permit?

You lose the independent safety check and the paperwork, and an unpermitted hookup can complicate an insurance claim after a fire or injury and be a red flag when you sell. It's a false savings — insist on the permit.

4 Does a proper interlock help when I sell my home?

It can. A permitted, inspected interlock with paperwork is a clean, documented feature, while an unpermitted hookup can raise questions at inspection or appraisal. The specifics depend on your local rules and the sale, so treat this as general information.

5 Do you give legal or insurance advice?

No — I'm a tech helper, not a lawyer or an insurance agent. I'll explain the by-the-book path in plain English and help you find the right people to ask, but the specifics come from your building department and your own insurer.

6 How is this different from backfeeding?

Backfeeding through a wall or dryer outlet isn't a recognized method — it can't be permitted or inspected, it's illegal, and it's deadly. A listed interlock does the same job the safe, legal, documented way.

Would You Rather I Just Help?

The code-and-insurance side sounds dull, but it's the part that quietly saves people from real trouble. I'll explain the by-the-book path in plain English, help you line up a licensed electrician who pulls the permit, and help you keep your paperwork straight — then point you to your building department and insurer for the specifics. This is general help, not legal or insurance advice. $99 flat for a visit.

Would you rather I just do this for you?

No shame in it — plenty of folks would rather hand it off, and that's what I'm here for. I'll come to your home, set it up right, and make sure it's working before I leave. Flat $99 per visit — no jargon, no upsell, and every visit is 30-day come-back-free.

Not a hardware job? I can often fix it remotely for $49 — a secure screen-share, up to 2 hours, that you watch the whole time and can end whenever (included free for $39/mo Support Plan members, and it counts toward the $99 if it turns out I need to come out).
