Breaker Panel Upgrades (Sub-panels)

Replacing outdated fuse boxes or adding a sub-panel to expand household power capacity.

Here’s what to know. This guide explains the type of work and why it can be needed. It is not a remote diagnosis or a do-it-yourself wiring tutorial.

What does this involve?

Replacing outdated fuse boxes or adding a sub-panel to expand household power capacity.

How does it work?

A subpanel distributes power to more branch circuits but does not itself create more electrical service capacity. Major panel work requires load review and safety planning.

What affects the job?

Panel rating, service size, available space, utility coordination, and local permit rules can all affect feasibility. We’ll review your goals and explain the next steps.

What should you tell us?

The warning signs you noticed, when they started, and photos from a safe distance. Do not open panels or covers to take pictures. You do not need to know the electrical terms. Tell us what you see and what you want to change.

Tell us what you need: You do not need to diagnose the problem or know the electrical terms. Share what you have noticed and what you would like to change. Our Knoxville team will help you understand the next step.
Electrical safety: Do not take apart switches, outlets, panels, wiring, or equipment based on online advice. If you notice heat, sparks, smoke, or a burning smell, stop using the affected equipment and contact a qualified electrician. For immediate danger or fire, call 911.

Keep safety in mind

The U.S. Consumer Product Safety Commission’s home electrical checklist explains common warning signs. For generator-related jobs, see the Electrical Safety Foundation International’s generator guidance. Share your concerns with our team for guidance on the next step for your property.
