Subpanel installation and panel relocation in Denver
A subpanel brings capacity to where the loads are, and a relocation gets the equipment out of a spot it never should have occupied.
A subpanel is fed from the main panel by a four-wire feeder: two ungrounded conductors, a neutral, and an equipment grounding conductor. Inside the subpanel the neutral bar stays isolated from the enclosure while the grounds land on a bar bonded to it, so normal return current never travels on grounding conductors. Feeder size follows the load the subpanel will actually serve rather than the size of the can it feeds.
Panel relocations come up when equipment ends up in a clothes closet, behind a finished wall, or in a spot without the working clearance the code requires in front of it. Moving it means extending every existing branch circuit into the new location, usually through a junction box or gutter left where the old panel stood, and re-identifying circuits as they land. The other half of the decision is capacity, because if the panel is already full or the service is undersized, a subpanel only postpones the real fix.
what is the difference between a subpanel and a main panel?
The main panel is where the service lands and where the neutral and the grounding system are bonded together. A subpanel sits downstream of it, fed by a breaker in the main, and keeps neutrals and grounds separated so return current has only one path back.
how many circuits can a subpanel hold?
Breaker spaces are one limit and the feeder is the other. A panel accepts as many breakers as it has spaces, but the load those circuits draw has to stay within what the feeder and its overcurrent device can carry, which is why the calculation comes before the panel gets picked.
can a panel be moved without rewiring the whole house?
In most cases, yes. Existing circuits are extended to the new location with splices made in an accessible box that stays reachable, which is far less invasive than pulling fresh cable back to every device in the house.
