Managing Loads on a Full-Panel Interlock
Last verified: September 2026
Because an interlock reaches your whole panel, you decide how much runs at once. Here's how to stay within your generator with a few easy habits — no wattage math required. Want a hand? (330) 200-8042.
Managing Loads on an Interlock, at a Glance
An interlock puts your whole panel on generator power, so you decide how much runs at once. The key idea: motors need a big jolt to start (a surge) and less to keep running, so bring the biggest surging load up first — often the furnace blower or a well pump — then add smaller loads one at a time. Listen to the generator; a bog-down means shed a load. In a long outage, cycle loads and keep the fridge and freezer closed so they coast. There's a printable 29-page version up top.
Common Questions
1 How do I know if I'm running too much at once?
Listen to the generator. A steady hum means you're fine; a strain, bog-down, or lights that dim and stay low mean you've asked for too much. Turn something off and it should recover.
2 What should I turn on first?
The biggest surging load — usually the furnace blower, or a well pump on a rural home — while the generator is fresh. Then add smaller loads one at a time, pausing between each.
3 Can I run my whole house on the interlock?
The interlock reaches every circuit, but your generator has a limit, so you run within it — often by cycling loads rather than running them all at once. Big electric heat and large appliances may simply stay off.
4 What's a starting surge?
The brief, larger jolt of power a motor needs the instant it starts, before settling to a smaller steady draw. It's the surges, not steady running, that overload a generator — so bring big motors up one at a time.
5 Do I have to count watts?
No. Biggest first, one at a time, keep the fridge closed, and listen to the generator. If you'd like your real numbers, our sizing guide shows how to find them.
6 What do I do if a breaker trips?
You drew a bit too much. Turn a load or two off, reset the breaker, and bring things up more slowly. If it keeps happening, lean on cycling or look at sizing.
Would You Rather I Just Help?
Load management sounds technical, but it's really just a few easy habits. I'll help you sort your circuits into a sensible order, label your panel, write a big-print load plan to tape beside it, and do a practice run so you learn your generator by ear. I don't do the wiring myself — that's a licensed electrician's job. $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).
