When Your Home or Business Needs Sub Panel Replacement or Installation
Identifying the need for sub panel replacement often becomes apparent through recurring electrical problems and safety concerns that indicate aging or inadequate electrical distribution systems. Frequent circuit breaker trips, especially those affecting multiple circuits simultaneously, often indicate panel capacity issues or deteriorating electrical connections that make replacement necessary for safe operation.
Critical safety indicators make sub panel replacement essential including panels with obsolete breakers that cannot be replaced when they fail, electrical panels showing signs of overheating like discolored breakers or burning odors, properties with insufficient circuit capacity that force dangerous use of extension cords and power strips, and electrical systems that cannot support modern appliance loads without constant breaker trips.

Fast, efficient, dependable, and very helpful. I called on Sears originally, but after my appointment was delayed multiple times throughout the day, I received a text telling me my appointment was cancelled for the day and rescheduled for four days later (and the diagnostic fee was twice what Justin charged!!!). I canceled them, scheduled Justin, who came one day later, at the scheduled time, and showed up on time again the day after we received the part! We highly recommend JCS Construction!!

You may need a sub panel if your main panel is full, you’re adding a new room or large appliance, or you want to separate circuits for convenience and safety.
-
The main panel connects directly to your utility service, while the sub panel gets its power from the main panel. A sub panel cannot disconnect the entire house power—it only controls specific circuits.
-
A sub panel should be installed in an accessible, dry, and ventilated area—commonly in garages, basements, or utility rooms. Local building codes usually dictate the exact placement.
-
This depends on your power needs. Common sizes are 60-amp, 100-amp, and 125-amp sub panels. Our team can calculate the load to recommend the right size.
-
There’s no strict limit, as long as the main panel can handle the load. Multiple sub panels are common in large homes or properties with detached buildings.
