The key decision

Available breaker spaces and available electrical capacity are different questions.

Separate the reason for the work

A damaged panel, an overloaded design and a lack of room for a new breaker are different findings. Ask the electrician to identify which finding drives each proposed change. A larger panel enclosure alone does not increase the utility service capacity.

Bring the future equipment list

Name near-term additions such as vehicle charging, cooking or a heat pump, together with models when available. The aim is a coordinated capacity assessment. Do not simply add appliance nameplate numbers yourself or assume that a neighbor’s installation applies to your house.

Read the complete route

Distance is only one part of installing a circuit. Finished walls, access, exterior penetrations, trenching and the point where repair work ends all matter. PG&E’s charging checklist recommends a qualified electrician’s capacity assessment before Level 2 equipment is installed.
