Common Mistakes, at a Glance

After helping many folks with backup power, the same mistakes come up again and again — and every one is avoidable. The two that can kill: backfeeding or DIY panel work, and running a generator anywhere but far outdoors. The rest — skipping the permit, mismatched sizing, overloading, never testing, stale fuel, faded labels — cost money and comfort. This guide gives the simple fix for each. There's a printable 29-page version up top.

Common Questions

1 What's the single most dangerous mistake?

Backfeeding — forcing generator power through an outlet — and DIY panel work. Both can kill and are illegal. Always use a licensed electrician, and never backfeed.

2 What's the most common everyday mistake?

Overloading the generator by turning on too much at once. The fix is simple: bring circuits up one at a time, biggest first, and cycle loads.

3 What mistake do people most regret?

For well homes, forgetting to plan for the pump and water — learned the hard way during the first waterless outage. Put the pump and stored water high on your plan.

4 Is it really so bad to skip the permit?

Yes — it means no independent safety check, and it can jeopardize an insurance claim and complicate selling your home. It's a false savings. Always insist on the permit.

5 What's the fix for a generator that won't start?

Prevention: keep fuel fresh (rotate it, use stabilizer) and exercise the generator now and then. Stale fuel and idle equipment are the top cause of no-starts.

6 How do I avoid all these mistakes?

Use a licensed electrician with a permit, size everything together, test and practice twice a year, run the generator safely outdoors, and keep fuel fresh and labels clear. Bill is glad to help with all of it.
