    For a restaurant, butchery, pharmacy or food shop, a cold room going down isn't an inconvenience — it's thousands of rands of spoiled stock and a broken cold chain. The electrical side is what keeps it running, and it deserves proper attention.

    Refrigeration needs dedicated power

    A cold room or commercial fridge runs continuously and surges on start-up, so it needs a dedicated, correctly-sized circuit with proper protection and an isolator, wired and certified by a registered electrician. Sharing a circuit invites tripping and stock loss; undersized wiring is a reliability and fire risk.

    Protecting the cold chain in load-shedding

    Put refrigeration on backup — an appropriately sized inverter/battery or generator with automatic changeover — so outages don't break the cold chain. Compressors surge on start-up, so the system must be sized for that, not just the running load. For larger loads, solar plus battery cuts both risk and running cost.

    Compliance protects your claim

    Commercial refrigeration wiring is part of your electrical installation and must be compliant and certified — important if you ever face a stock-loss insurance claim. See commercial electrical and backup solutions.
