ELECTRICAL PANEL Shopping Guide (In-Depth)

Live electrical equipment is dangerous. A licensed pro will evaluate hazards, pull permits, and follow code and manufacturer instructions. Do not remove panel covers, swap breakers, or work energized equipment yourself.

Corrosion, loose lugs, and outdated designs increase arc and overheating risk. If rust, pitting, or moisture is present inside the enclosure, replacement is often safer than repair.

Nuisance trips may indicate deteriorated breakers, overloaded circuits, or internal panel faults. A pro can test fault currents, balance loads, and determine if replacement or circuit redesign is warranted.

Discoloration, soot, or melted insulation suggests arcing or overheating at connections or breakers. Shut off power if safe to do so and call an electrician immediately for evaluation.

Age, humidity, and load growth shorten useful life. Upgrading older equipment improves safety, fault protection, and compatibility with modern devices.

Allocate spaces and capacity for EV charging, solar interconnection, heat pumps, or backup power. Consider a larger ampacity or a subpanel to avoid outgrowing the new equipment.

Moving from 100A to 200A service, for example, can require utility coordination, a new meter base, and permits. Lead times may involve the city and the energy provider, so plan ahead.

A clean design considers interconnection points, transfer switches, rapid-shutdown, and load priorities. Label equipment and provide clear one-line diagrams for future service.

Type 1 or Type 2 SPDs protect sensitive appliances and electronics from voltage spikes. Follow manufacturer torque specs, breaker sizing, and bonding/grounding requirements.

Smart panels provide circuit-level monitoring and remote control. Load-shedding can reduce peak demand charges or help keep critical loads powered during an outage.

Copper resists oxidation and maintains better spring tension at terminations. If using aluminum, ensure anti-oxidant compounds and proper torque are used per manufacturer instructions.

Smart breakers provide usage data and remote trip notifications, and some support scheduling or load management. Confirm compatibility with your panel and any smart home ecosystem.
