Kitchen electrical load for a 60-cover restaurant

Key Takeaways

• Commercial kitchens are explicitly larger-scale operations than domestic ones, equipped with heavier-duty equipment such as walk-in refrigeration and industrial dishwashing machinery, not a bigger version of a home kitchen's appliance mix.
• A 60-cover restaurant's electrical load is driven primarily by refrigeration, cooking, and warewashing equipment operating simultaneously during service, which is a fundamentally different load profile from a residential kitchen's intermittent single-appliance use.
• Nameplate ratings on commercial kitchen equipment reflect worst-case draw, not typical running load, so the board sizing question is the same demand-factor problem as any other commercial electrical design: realistic peak, not sum of every rating.
• Kitchen equipment schedules change late in a restaurant fit-out as menu and supplier decisions firm up, which makes early electrical infrastructure decisions (spare board capacity, feeder sizing) a hedge against late-stage equipment changes rather than a fixed, one-time calculation.

A 60-cover restaurant kitchen isn't a home kitchen scaled up by a multiplier, it's a categorically different piece of electrical infrastructure, built around equipment that runs continuously through service rather than intermittently, and sized for a load profile that has no domestic equivalent.

Why commercial kitchen equipment is a different category

Commercial kitchens are described as generally larger and equipped with bigger, heavier-duty equipment than a residential kitchen, with a large restaurant's kitchen typically including elements like a walk-in refrigerator and a large commercial dishwashing machine as standard fixtures (Wikipedia, kitchen, retrieved 2026-09-10). Neither of those pieces of equipment has a meaningful residential equivalent in electrical terms: a walk-in refrigeration unit runs continuously, not intermittently like a domestic fridge cycling on and off, and a commercial dishwasher's electrical and often direct water-heating load has no comparison point in a household appliance schedule.

The three load categories that actually drive the number

For a 60-cover restaurant, the electrical design load is dominated by three categories operating together during service: refrigeration (walk-ins, prep-line cold storage, and beverage refrigeration, all running continuously), cooking equipment (ranges, ovens, fryers, and any electric cooking line, drawing heavily and often simultaneously during peak service), and warewashing (commercial dishwashing equipment, frequently including its own water-heating element). Unlike a domestic kitchen where appliances are used one or two at a time, a working restaurant kitchen at service runs meaningful loads across all three categories concurrently, which is the core reason a residential-scale sizing assumption fails here.

Nameplate rating vs realistic running load, the same principle applied to a kitchen

Commercial kitchen equipment nameplates reflect the equipment's maximum rated draw, not its typical running load during actual service, which makes this the identical demand-factor problem that applies to any electrical design: summing every piece of equipment's nameplate rating produces an inflated, unrealistic figure, while a properly applied demand factor for kitchen-specific equipment and usage patterns produces the number the board should actually be sized against. Run the kitchen's full equipment schedule through the electrical load calculator with an appropriate commercial-kitchen demand factor, rather than defaulting to the sum of every appliance's rated wattage, which will typically overstate the real design load by a meaningful margin.

Why the equipment schedule keeps moving, and what that means for the board

A restaurant's final kitchen equipment list is often one of the later decisions in a fit-out programme, tied to supplier selection, menu finalisation, and sometimes last-minute changes to the concept itself. An electrical board sized tightly against an early, provisional equipment schedule risks being wrong by the time the kitchen actually opens, if the final equipment mix draws more than the early estimate assumed. Building a deliberate spare-capacity margin into the board spec, rather than sizing it exactly to the earliest available equipment list, is the practical hedge against this, since re-opening a finished board installation to add capacity later is far more disruptive than allowing for it from the start.

Frequently asked questions

Is a commercial kitchen's electrical load mostly cooking equipment, or something else?

Cooking equipment is a major component, but refrigeration (particularly walk-in units, which run continuously) and warewashing equipment both contribute substantial, ongoing load as well. A design that only accounts for the visible cooking line and underestimates continuous refrigeration and dishwashing load will undersize the board.

Should the board be sized to the kitchen equipment supplier's full nameplate schedule?

Not directly, that figure represents worst-case simultaneous draw across every piece of equipment, which real kitchen operation doesn't produce. A demand-factored figure appropriate to commercial kitchen operation, prepared by a qualified electrical consultant, is the correct basis for board sizing.

How much spare capacity should be built in if the equipment schedule isn't finalised yet?

There's no universal figure, it depends on how firm the early equipment list actually is and how far along the fit-out programme sits. The key point is treating any margin as a deliberate, stated decision rather than assuming an early estimate will hold exactly through to opening.

The bottom line

A 60-cover restaurant kitchen's electrical load is driven by continuous refrigeration, concurrent cooking equipment, and warewashing operating together during service, a profile with no domestic equivalent to scale up from. Size the board against a proper demand-factored calculation on the realistic equipment schedule, with deliberate spare capacity for the fact that the final equipment list often isn't locked until late in the fit-out. Coordinating that board spec alongside the rest of the kitchen's mechanical and fit-out drawings through an engineering fit-out planning tool helps catch a mismatch between the electrical design and the final equipment schedule before the contractor is on site, not after.
