When You Actually Need a Panel Upgrade
A 'heavy-up' - moving from 100-amp to 200-amp service - is one of the most common requests we get. You typically need one if you're adding an EV charger, a heat pump or mini-split, a hot tub, an addition, or if your existing panel is full and there's no room for new circuits.
If your panel is a Federal Pacific Stab-Lok or a Zinsco, the answer is simpler: replace it. Both panels have documented histories of breakers failing to trip during overcurrent - a known fire hazard and one that most insurers now flag during inspection.
