How Is Electrical Design Done for a Coin-Operated Laundromat?
By Jeremy Mills, CEO & Founder, Apex Grid Engineering — USAF Veteran. · Updated 2026-09-15
Coin-operated laundromat electrical design provides dedicated manufacturer-specified circuits for every washer and dryer, panels and service sized for Saturday-peak coincident load, and separate clean power for lighting, security, and payment systems.

Panels, phases, and spare capacity
I organize the distribution around the equipment rows: panelboards placed to minimize long homeruns, three-phase loads balanced across phases, and every breaker labeled to its machine. The schedule documents voltage, amperage, and wire size per the manufacturer — mixed 120V controls and 208/240V power are normal in this equipment, and getting a voltage wrong is an expensive mistake. I leave generous spare breaker spaces and spare panel capacity, because laundromat owners reconfigure equipment constantly, and a panel with no room turns a simple machine swap into an electrical project.
Power quality for the money-handling side
The machines that take money deserve the cleanest power in the building. I put payment systems, point-of-sale, cameras, and network gear on dedicated circuits fed from panels separated from the big motor loads, and I specify surge protection at the service and at sensitive panels — laundromats see their share of utility transients. Grounding follows the equipment requirements, and where the owner runs card systems, I coordinate with their IT on any power conditioning needs. A payment terminal that reboots during a transaction costs more in customer trust than the surge protector ever cost.
Lighting and life safety essentials
The electrical design carries the store's safety story: • Uniform, generous interior lighting levels with no dark corners — designed above code minimums • Entrance, facade, and parking area lighting on photocell or scheduled control • Emergency egress lighting and exit signs per code, tested and documented • Lighting circuits arranged so one failure never darkens a whole zone • Tamper-resistant fixtures and controls in public areas • Receptacles coordinated with folding tables, vending machines, seating, and cleaning needs
