Adding Capacity Where You Need It

We install subpanels to distribute power safely throughout your property. Our electricians perform load calculations before every installation to ensure your main panel can support the additional circuits. We typically install 100-amp or 200-amp subpanels depending on your needs. All work includes proper grounding, bonding, and weatherproof enclosures when required. We pull permits and schedule inspections so your installation meets NEC Article 408 requirements. Our team routes feeder cables through walls or conduit with minimal disruption to your home.

Quality Materials and Methods

Built to Code and Built to Last

We use Square D, Siemens, or Eaton panels based on your existing system. Each subpanel receives its own shutoff breaker at the main panel. We label every circuit clearly and provide you with a circuit directory. Our installations include proper wire sizing for voltage drop over distance.

Common Questions

Residential Electrical FAQs

Common questions from Triangle homeowners about residential electrical services. Don’t see yours? Call us directly — we’re happy to help.
How do you determine what size subpanel I need?
We calculate the total anticipated load for all circuits you plan to run from the subpanel. This includes lighting, outlets, and any large appliances or equipment. We also verify your main panel has adequate capacity and an available breaker slot for the feeder. Most residential detached garages work well with 60 or 100-amp subpanels.
It depends on the location. Detached structures like garages or sheds require their own grounding electrode system per NEC 250.32. We install ground rods and bond them properly. For subpanels inside the same building as your main panel, we run a ground wire back but keep ground and neutral buses separate in the subpanel.
All subpanel installations require an electrical permit from your local building department. We pull the permit before starting work and schedule the required inspection after completion. The inspector verifies proper wire sizing, grounding, panel labeling, and clearances. Permits typically cost between seventy and one hundred fifty dollars depending on your municipality.
Yes, we install subpanels in finished spaces regularly. We route feeder cables through existing walls or run them in surface-mounted conduit if necessary. The panel requires thirty inches of clearance in front and sufficient headroom per code. We patch and paint any access holes we create during installation.
Most straightforward installations take four to eight hours depending on distance and access. Running wire through finished walls adds time. We complete the work in one day for standard applications. Complex runs requiring extensive conduit or outdoor trenching may take two days. Inspection scheduling adds a few days to the overall timeline.

Legally, that depends on your local jurisdiction. Some areas allow homeowners to do their own electrical work with permits. Others require licensed electricians for all work. We install the subpanel with extra spaces so you have room for future circuits. We recommend having a professional handle any additions to ensure safety and code compliance.
