Commercial Service Upgrades & Rewiring
Buildings outgrow their electrical service quietly. A panel fills, a subpanel gets added, then another, and eventually there is nowhere left to land a breaker for the equipment you just bought. An upgrade replaces the service entrance and the distribution with capacity sized for the building as you use it now, and leaves room for the next addition instead of consuming it.
Scope of a commercial upgrade
- A load study of what the building actually draws, measured rather than estimated
- New service entrance, meter arrangement and main distribution
- Utility coordination for the cut-over, planned around your operating hours
- Subpanels placed where the load is, instead of one crowded panel room
- Full or partial rewiring where the branch circuits are the real limit
- Permits, inspection, and an updated schedule for the building as it now stands
Tenant build-outs and additions
A new tenant space, a warehouse addition and a mezzanine office all land on the same question: is there capacity, and where should the new distribution sit. We answer that before the walls go up, because a subpanel positioned to suit the drawing rather than the load is a painful thing to move later.
Planning the outage
The cut-over is the part that needs real planning. We work out how long the building has to be dark, whether any of it can run on a temporary feed, and when that window hurts you least. Most cut-overs happen overnight or on a weekend, coordinated with the utility well in advance.
Frequently asked questions
How do we know the building needs more electrical capacity?
The signs are a full panel, repeated main trips, subpanels fed from subpanels, and voltage sag when large equipment starts. A load recording over a week settles the question.
How long is the building without power during a cut-over?
Usually a matter of hours, scheduled into a night or a weekend. Where part of the load has to keep running, we arrange a temporary feed for it.
Can the upgrade be done in phases?
Yes. New distribution can be installed alongside the old and circuits moved across in stages, which is often the only workable route for a building that cannot close.
Does commercial service work need a permit and inspection?
Always. Service and distribution work is permitted and inspected on both sides of the river, and we handle both as part of the job.
Who talks to the utility about a larger service?
We do. The application, the load information and the scheduling of the disconnect and reconnect are all ours to coordinate.
