Portable Hookups

What a portable generator hookup includes

A portable generator only helps when it can feed the panel safely. We mount a weatherproof inlet, add an interlock kit or manual transfer switch, and keep generator power and utility power from ever meeting. Common work on lake houses around Lake Winnipesaukee and Squam Lake.

Cost Higher up front for equipment, installation, and fuel work. Lower for both the generator and the electrical work. The unit goes with you.

Questions

Common questions about portable generator hookups

Do I need an interlock kit or a manual transfer switch?

Both keep generator power and utility power from ever meeting. An interlock is a sliding plate on your existing panel. A manual transfer switch is a separate piece of equipment that moves selected circuits over. We recommend the right option after we see the panel.

Will the hookup work with any portable generator?

Yes. For portable hookups the generator is usually yours already. The inlet, interlock, or transfer switch we install works with any make that matches the inlet amperage.

Can you install a portable hookup at a seasonal home?

Yes. Lake houses around Lake Winnipesaukee and Squam Lake are a large share of this work. You still connect and start the unit by hand when you are there for an outage.

Is a portable hookup safer than running extension cords?

Yes. A code-compliant inlet and interlock or transfer switch feeds the panel the right way and prevents backfeeding the utility. Extension cords cannot do that job.

How do I get a portable hookup estimate?

Call or text 603-619-8875, or use the estimate form. Same-day response during business hours when the schedule allows. Send a panel photo if you have one.
