Subpanel Installation & Replacement

A subpanel does not create additional utility service capacity by itself; it distributes power from the existing electrical system. For that reason, a responsible plan begins with the main service rating, existing demand and the loads that will be served. An ADU, workshop, HVAC upgrade or EV equipment may require different feeder and panel considerations. Slazik Electric can evaluate the proposed panel location, available pathway, grounding and bonding requirements, feeder conductors and the number of circuits needed. Replacement may be recommended when an existing subpanel is damaged, crowded, obsolete or unsuitable for the planned work. The finished installation should provide appropriate working clearance, clear circuit identification and room for the intended project. If the existing main service cannot support the proposed loads, visitors should be directed to the established electrical panel upgrade page. This distinction helps customers understand the difference between adding distribution space and increasing overall electrical capacity.
