Choosing a Service

Panel Upgrade or Service Change?

These get used interchangeably, but they're not the same job. A panel upgrade replaces the panel itself — usually because it's worn out, outdated, or unsafe — without necessarily changing how much power comes into your home. A service change increases that amount, typically from 100 amps to 200 amps, which means new equipment from the street to the panel and coordination with your utility.

Most homes built before the 1980s have 100-amp service, which met code at the time but is often the limiting factor today. Around here we still find plenty of 60-amp services, and older ones often have no main breaker at all — no single switch that shuts the whole house off. Not sure which one you need? Tell us what you're trying to do — add a circuit, run a new appliance, get the house ready for something bigger — and we'll tell you which job actually solves it.

Worth Knowing

Signs Worth Calling About

A few things are worth a call, whether your panel's in a Williamsport rowhome or a place out in the township: breakers that trip more than once in a while, a panel that's full with no room for a new circuit, or a panel still running on fuses instead of breakers. None of these mean something's about to go wrong — they just mean it's worth having someone look.

It also matters what's actually in the panel. A few older brands get flagged by electricians and inspectors:

  • Federal Pacific (FPE) Stab-Lok — widely flagged by electricians, though never formally recalled. The CPSC investigated it in the early 1980s and closed the case without ruling on whether it was safe.
  • Zinsco (also sold as Sylvania or GTE-Sylvania) — breakers can fuse to the bus bar and stay energized even when switched off.
  • Challenger — unlike FPE and Zinsco, this one was actually recalled, once in 1988 and again in 2014 for a separate issue.
  • Pushmatic — not flagged as a fire risk, just old enough that replacement parts are getting hard to find.
  • Plain fuse boxes — not unsafe by design, but common in homes built before the 1960s and usually undersized for how a house is used today.

Looking Ahead

What This Unlocks

100-amp service was completely normal for most of the last 60 years. It's also usually the ceiling. Add a few of today's bigger loads — an EV charger, a standby generator, a solar array, or a mini-split system — and a 100-amp panel runs out of room fast.

A service change isn't always required for these. Sometimes there's enough capacity left in the existing panel, sometimes there isn't. Either way, it's worth checking before you buy equipment, not after.

Process

Permits & the Utility

A panel upgrade or service change needs a permit and inspection like any other electrical work — that part's the same as everything else we do. A service change adds a second step: the utility owns the meter and the line feeding it, so any increase in service size has to be coordinated with them, not just permitted with the township.

Otta Electric is authorized under PPL's Fast Track Program, which lets us make that service connection ourselves on qualifying overhead services up to 200 amps — so the job isn't held up waiting on a separate utility visit. Underground services, larger services, and anything outside the program still go through PPL the usual way, and we handle that coordination too.

Questions

Frequently Asked

A panel upgrade replaces the panel itself, often at the same amperage. A service change increases how much power comes into the building — usually 100 amps to 200 — which means new equipment from the street to the panel and coordination with the utility.

Open the panel door and check the cover or the breakers — Federal Pacific panels are usually stamped "Federal Pacific" or "Stab-Lok," and Zinsco panels may say Zinsco, Sylvania, or GTE-Sylvania. Not sure? Send us a photo and we'll tell you.

Yes. Both fall under Pennsylvania's Uniform Construction Code and require a permit and inspection. Service changes also involve PPL, since they own the meter and the service line. We handle the permit either way.

It authorizes certain electrical contractors to make the final service connection themselves on qualifying jobs — single-phase overhead services up to 200 amps — instead of scheduling a separate utility visit. We're authorized under it, which usually means less waiting on a service change.

Yes, briefly — power has to be off while the old panel is disconnected and the new one is wired in. Usually a few hours, not a full day. We'll walk you through what to expect before we start.

It can — having capacity available makes those installs simpler down the line. But it's not always necessary first. We'll check what you actually have before recommending an upgrade.
