Electrical Panel Upgrade for Fort Shafter homes and businesses

Electrical Panel Upgrade in Fort Shafter starts the same way every time: we look at what is actually installed before quoting anything. 100 to 200 amp service upgrades, breaker box replacement and sub panels sized for what you actually run. On Oahu that matters, because two houses on the same street rarely share a wiring history.

Newer Fort Shafter construction has the opposite problem: the wiring is fine but the load has grown. Add an EV, a mini split and an induction range and a 100 amp service runs out of room fast. A load calculation tells you whether you need an upgrade or just a rearranged panel.

Oahu carries most of the state's load, and it shows in the wiring. We work on 1950s plantation cottages, high-rise condos with shared risers, and newer tract homes out toward the leeward side.

What Fort Shafter customers say

★★★★★

Smart switches through the whole house. They added neutrals where the boxes didn't have them instead of telling me it couldn't be done.

Jodi N., Fort Shafter
★★★★★

Sub panel for the ohana unit. Clean work, labelled, and they pulled it in a way that leaves room for more later.

Electrical Panel Upgrade in Fort Shafter: frequently asked questions

How do I know my Fort Shafter panel needs upgrading?
Full breaker slots, double-tapped breakers, a fuse box, frequent tripping, a warm cover, scorch marks, or a plan to add an EV charger, AC or a range. Any one of those is a reason to look.
How long does a panel upgrade take in Fort Shafter?
Most residential upgrades are a one day job, with power off for part of it. Utility coordination and inspection can add scheduling time, and we handle that for you.
What size service should I get in Fort Shafter?
200 amp is standard for most homes now, especially with an EV or a heat pump in the plan. We run a load calculation rather than guessing.
Can you replace just the breaker box in Fort Shafter?
Sometimes, if the service and meter are in good condition. If the service entrance cable is undersized or corroded, replacing only the box leaves the real bottleneck in place.
Do I need a permit for a panel upgrade in Fort Shafter?
Service work is permitted and inspected. We take care of the paperwork and the inspection appointment as part of the job.
Will my power be off all day in Fort Shafter?
Not usually all day. We plan the outage window with you in advance so you can move anything temperature sensitive first.
Do you charge extra for nights, weekends or holidays in Fort Shafter?
After-hours work in Fort Shafter is quoted at a flat price before we start, so you know the number before anyone drives out. There is no meter running while we diagnose.
What areas around Fort Shafter do you serve?
We cover Fort Shafter and the wider Oahu area, plus the rest of Hawaii. If you are just outside Fort Shafter, call (888) 633-7804 and we will confirm coverage in one minute.
