Panel Brands and Known Safety Issues

If you live in a Denver-area home built between roughly 1955 and 1990, there’s a meaningful chance you have a Federal Pacific Electric (Stab-Lok) or Zinsco panel. Both have well-documented histories of breakers that fail to trip under overload conditions — essentially, the safety mechanism doesn’t work reliably. Electricians who open these panels for any repair often recommend replacement rather than repair, because individual breaker replacement doesn’t resolve the underlying bus bar and socket design issues. If your home has one of these panels, a professional evaluation is worth scheduling proactively rather than waiting for a problem to force the conversation.

What a Professional Panel Installation Includes

A licensed electrician doing a panel replacement or significant repair will: calculate your home’s current and future load requirements, select a properly rated panel with room for expansion, pull the required permit, coordinate the utility disconnect and reconnect, make all connections to manufacturer torque specifications, install proper labeling, verify grounding and bonding, and schedule the inspection. That process protects you legally, financially, and physically — and it’s the only way to know the work was done right.

Done’s licensed electricians have been handling panel repairs and full replacements across the Denver metro since 1999. Visit our panels and wiring page to learn more about what’s involved, or reach our emergency electricians if you have a panel issue that can’t wait. Financing is available for panel upgrades.

What Can Go Wrong With DIY Panel Work

The most common problems from unprofessional panel work aren’t always immediately obvious — which makes them more dangerous, not less. Double-tapped breakers (two wires on a single breaker terminal rated for one) are a fire risk that can smolder for years before causing an incident. Undersized wire for a breaker’s amperage rating means the wire can overheat before the breaker trips. Improper torque on breaker and lug connections causes resistance heating at the terminal — a leading cause of panel fires. Neutral and ground wires mixed on the wrong bus bars create shock hazards. A licensed electrician using calibrated torque tools and following manufacturer specs avoids all of these.

Colorado Licensing Requirements

Colorado law (Title 12, Article 23 of the Colorado Revised Statutes) requires that electrical work be performed by or under the direct supervision of a licensed electrician. Panel work specifically requires a permit in virtually every municipality on the Front Range, and the work must be inspected by a city or county electrical inspector before the panel is re-energized. An uninspected panel repair or installation can:

  • Void your homeowner’s insurance policy’s fire coverage if the cause is traced to unpermitted electrical work
  • Create a required disclosure obligation when you sell your home
  • Result in fines from the municipality
  • Require expensive correction work before a buyer’s lender will approve a mortgage

Why Panels Are Uniquely Dangerous

Every other electrical task in your home can be made safe by turning off the right breaker. Panel work cannot. The service entrance conductors — the large wires feeding power into the top of the panel from the utility — are always energized, even with the main breaker off. The only way to de-energize them is to have the utility disconnect power at the meter, which requires coordination and a licensed electrician to request. Working around live conductors carrying 200 amps at 240 volts without proper training and protective equipment is genuinely lethal — this isn’t a risk category where extra caution makes it manageable.

Having a licensed electrician for electrical panel repairs and installations isn’t just important — it’s required by law in Colorado and nearly every other state. The panel is the nerve center of your home’s electrical system, and work done incorrectly there can cause house fires, electrocution, or a failed home inspection years down the road. Beyond legality, the technical demands of panel work — load calculations, proper wire terminations, breaker compatibility, and grounding — are not forgiving of guesswork.
