Choosing a Transfer Switch, at a Glance
Choosing an automatic transfer switch is easier than it sounds if you take it in order. Start with what you'd keep running, then walk the big choices — automatic vs. manual, whole-home vs. managed, the generator and fuel, and the features that matter — and let a licensed electrician size and install it. This guide is the calm overview that ties it all together. There's a printable 29-page version up top.
Common Questions
1 Where do I start when choosing a transfer switch?
With your must-run list — what you'd keep running in a long outage. Every other choice, from size to type, flows from that list. You bring it; your electrician sizes the system to it.
2 Do I need whole-home coverage or a managed system?
For most homes, a managed system covers your needs nearly seamlessly for less. Whole-home is worth it if you want zero compromise and the budget allows.
3 What features actually matter?
Quality, listed equipment from an established maker; load management if you want a smaller generator; monitoring for peace of mind; and a real warranty with local support.
4 How is the right size decided?
Your electrician sizes the generator and switch to your must-run list, accounting for the big starting surge of motors like the well pump. You don't do the math — you bring the list.
5 How do I find a good installer?
Look for a licensed electrician experienced with backup systems who pulls permits, explains things plainly, and sizes honestly rather than always upselling. I'm glad to help you find and vet one.
6 Can I install it myself to save money?
No. It's licensed, permitted panel and generator work — often gas work too — and doing it wrong is dangerous. I'll help you line up a trustworthy pro instead.

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).
