Helpful Answers
Subpanels Questions
Clear information helps you plan electrical work safely and confidently. Project requirements vary by property and jurisdiction.
Does a subpanel increase my service capacity?+
No. A subpanel adds distribution space; the upstream service and feeder must still support the calculated load. A service upgrade or load-management plan is evaluated separately.
What determines subpanel installation cost?+
Feeder length, wiring route, panel location, available upstream capacity, wall access, required grounding work and permit scope affect the proposal.
Can a detached garage use a subpanel?+
Often yes. The design depends on the building, feeder route, grounding requirements and planned loads. Gridline evaluates those conditions before selecting equipment.
