The key decision
Available breaker spaces and available electrical capacity are different questions.
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.
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.
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.
Put it into practice
| What the proposal says | What to ask | Why it matters |
|---|---|---|
| Panel replacement | Is this a condition issue or a capacity issue? | Defines the problem being solved |
| Service upgrade | What utility-side work is included? | Separates property work from utility work |
| New circuit | Where does the route go? | Reveals access and finish repair |
| Load management | Which approved system and operating limits? | Clarifies when charging may slow or pause |

All guides in this topic
Separate four electrical questions before accepting a proposal for a larger panel or utility service.
Compare 200A upgrade proposals by utility work, meter location, route, restoration, and outage responsibilities before comparing totals.
Plan occupied-home rewiring around real circuit boundaries, daily living needs, dust control, access, and finishing responsibilities.
Before insulating an older home, distinguish active knob-and-tube from abandoned remnants and coordinate documented electrical work.
Compare aluminum branch-wiring proposals by repair method, circuit coverage, access, retained wiring, and insurer documentation.
Understand subpanel enclosure ratings, feeder limits, upstream capacity, and the access work hidden in a larger-panel quote.
Recurring breaker trips require a documented circuit and equipment diagnosis, especially when a previous breaker replacement did not solve the symptom.
Map flickering and partial power by extent, preserve the event history, and coordinate utility and electrician findings without opening equipment.
A nonresetting GFCI and several dead outlets require a supply and protection map, with model-specific interpretation and a documented diagnosis.
Treat electrical burning odor and abnormal buzzing as response and diagnosis questions, with clear emergency boundaries and repair records.
Storm-damaged service equipment needs a coordinated safety, customer repair, building restoration, inspection, and utility reconnection plan.
A prelease electrical review connects equipment needs, tenant feeders, building capacity and landlord responsibilities before the opening date is committed.
Avoid an electrical mismatch by reviewing the actual appliance documentation, existing supply and kitchen connection schedule before purchase.
Distinguish compatibility, low-end dimming, programming and electrical problems before replacing commercial lighting by guesswork.
Connect the permitted lighting design, installed controls, certified acceptance testing and facility operating records before the final inspection.
Map circuits, connected loads, UPS limits and the complete network path to diagnose reboots and create a useful office power scope.
