How long does an electrical panel last?
How long an electrical panel lasts
Published service life: 60 years. Roots plans for: year 60.
Service life is a planning horizon, not an expiry date. It tells you when to start budgeting, get a second quote, and stop paying for repairs on something near the end — not the day it stops working.
What changes this
Age is the weakest signal on this component. Panels are far more often replaced for capacity — adding a heat pump, an EV charger, a subpanel — than for wear. Some legacy brands are also a recognised fire hazard at any age and should be assessed on brand rather than on years, which is a question for a licensed electrician.

Service-life figures are typical estimates drawn from published industry references. Where a second reference covers the component, the figure is cross-checked against it and any disagreement is set out above; where only one reference covers it, that is stated. Actual life varies with installation, water quality, climate, and maintenance, and these figures shouldn't be relied on for insurance, lending, or warranty decisions.
Maintenance is what decides where in the range you land
The published range is wide for a reason: two identical units, installed the same day, routinely fail years apart. What separates them is upkeep.
For an electrical panel, the tasks that matter most:
- Test GFCI outlets — GFCI protection fails silently with age. The test button is your only way to know.
Roots tracks the age of every component in your home alongside the upkeep that extends it, so the replacement is a planned expense instead of an emergency.
Frequently asked questions
- How long does an electrical panel last?
- Typically 60 years. Roots plans a replacement at year 60.
- When should you replace an electrical panel?
- Roots plans for year 60, measured from installation. That is a planning horizon, not an expiry date: budget for the replacement then, and keep using it while it works.
- What shortens the life of an electrical panel?
- Age is the weakest signal on this component. Panels are far more often replaced for capacity — adding a heat pump, an EV charger, a subpanel — than for wear. Some legacy brands are also a recognised fire hazard at any age and should be assessed on brand rather than on years, which is a question for a licensed electrician.
