An upgrade can mean a larger panel, an added subpanel, or a larger service with a new meter base. Service upgrades involve your electric utility, which owns the meter and the connection to its lines. The utility has its own approval steps and schedule, and most of these jobs need a planned power shutdown. We set that time with you well ahead, so staff and tenants know when the power will be off. ## Electrical for tenant build-outs A new layout needs power where the desks, counters and equipment will be. Build-out electrical work usually means new circuits and outlets, lighting with switches or sensors, and dedicated circuits for kitchen equipment, medical equipment or server racks. Before any of that, the existing panel gets checked for room. If the tenant's equipment needs more capacity than the space has, you'll know at the proposal stage, not after the walls are closed. The electrical work is scheduled with the plumbing and HVAC. Rough-in happens while the walls are open, devices and fixtures go in after finishes, and the work goes through the inspections the job requires. ## Who does the electrical work? Electrical work on your job is done by licensed and insured techs. It's scheduled with any plumbing and HVAC on the job, so scope, scheduling and closeout go through one point of contact. Root House Mechanicals is licensed and insured, and plumbing is done under Tennessee Limited Licensed Plumber 5279. ## How a commercial electrical job works 1. **Walkthrough.** We look at the panels, the size of the service, the circuits involved and how the space is used. 2. **Proposal.** A written scope and a firm price before any work starts, noting any permit, inspection or utility step the job needs. 3. **Schedule.** We set dates with you, including any power shutdown and who needs notice. We work Monday to Friday, 8 a.m. to 5 p.m. 4. **Work.** Rough-in, then devices and fixtures, with one point of contact the whole way through. 5. **Closeout.** The circuits are tested, the panel directory is updated for any changes, and you get the manuals and any inspection records. ## How to request a bid Call or text (615) 426-9344 to talk it through, or email the scope with the details below.

Yes. Panel replacements, added subpanels and service upgrades are part of the commercial electrical work we handle. A service upgrade also involves your electric utility, which handles the meter and the connection to its lines. ### Will we lose power during the work? Some work can be done with the rest of the building powered, and some needs a planned shutdown. We'll tell you which in the proposal and set any shutdown time with you in advance. ### Do you install EV chargers for businesses? Yes. Level 2 chargers for staff or customer parking, including the circuits and any panel capacity they need. How many chargers your service can carry depends on its size and what else it runs. ### Does commercial electrical work need a permit? Most new circuits, panel work and build-outs need a permit and an inspection. The proposal says what your job needs. ### Can you switch our lighting to LED? Yes. Replacing older fluorescent or high-intensity fixtures with LED fixtures or retrofit kits is common, and it pairs well with occupancy sensors or timers.
