Panel upgrades
When the panel is the bottleneck.
A panel is sized for the house the day it is put in. A car charger, a generator, an addition, a workshop or a hot tub can each ask for more than an older panel has room to give.
The signs are familiar: breakers that trip, lights that flicker, no open spaces for a new circuit. We look at the panel and the service, tell you what they can carry, and upgrade the service, replace the panel or add a sub-panel where the new load lives.
The two panels at the top of this page went in side by side in a garage wall, with the drywall opened above and below them for the new cable.
The electrician's eye
Where a panel upgrade fits
Before a car charger
A Level 2 charger needs its own circuit, so the panel check comes first.
Before a generator
A generator connects through a transfer switch at the panel.
Before an addition or a shop
New rooms and new tools mean new circuits, and a sub-panel puts the breakers where the work is.
