What it means
Panelboards hold the breakers that switch off a circuit when there is a fault or overload. Commercial panels are fed from a main distribution board and serve lighting, receptacles, mechanical equipment and other loads. A panel schedule lists what each breaker controls.
Panels vary by voltage and phase, and their size is matched to the load.
Why it matters
Panels are the control point of the electrical system. If one is full, undersized or poorly labelled, adding circuits becomes slow and costly. Accurate labelling also affects safety, since a worker must know what a breaker controls before working downstream.
Panel space is a common limit in older buildings.
How HSM handles it
HSM's electrical crew sizes, installs and labels panelboards as part of tenant fit-outs and renovations. We check available spare capacity before design is final, and we provide clear, printed panel schedules at handover.
Where an existing panel is full, we assess whether a sub-panel, a relocated feed or a new panel is the better option. Because our electricians are led by a Master Electrician, the work is checked by someone with deep experience in the trade.
Panel locations also have clearance requirements that must be built into the layout.
What to plan for
Request updated panel schedules after any electrical changes. Keep the paper copy in or near the panel and a digital copy with your facilities records.
Ask your landlord who owns and maintains the panels in your space. Ownership affects who can approve changes and who must be notified of shutdowns.
