What do you need to know?
In the catering industry, choosing the right equipment isn’t just about performance or brand reputation — it also comes down to power. Commercial kitchens often require appliances that can handle heavy, continuous workloads, and that means understanding the difference between single-phase and three-phase electricity.
While many smaller items, such as microwaves or counter-top fryers, run perfectly on a standard single-phase supply, larger equipment like combination ovens, walk-in refrigeration, or high-capacity dishwashers may demand the stability and strength of three-phase power. Knowing which supply your kitchen has — and which your equipment needs — can save you from costly mistakes, downtime, and safety issues.
What is the difference between single and three phase?
The main difference between single-phase and three-phase power is the amount of electricity they can deliver and how steadily they deliver it.
Single-phase is the type of supply most homes have — it’s good for smaller appliances and light use, but the power can fluctuate slightly as it flows.
Three-phase, on the other hand, delivers a much more constant and powerful supply, making it ideal for heavy-duty equipment that needs to run smoothly without interruptions.
In short, single-phase is suited to everyday, lower-energy items, while three-phase is built for bigger, more demanding machines.
Should I choose single or 3 phase catering equipment?
When planning a professional kitchen, choosing between single phase and three phase appliances doesn’t have to be confusing. Both can work perfectly but the right choice depends on your kitchen’s setup.
Single Phase Appliance
Ideal for plug-in machines, single phase appliances are easy to install and replace. If most of your existing kitchen equipment is single phase, simply match your new appliances to the same rating, check volts, watts, and amps before buying.
Three Phase Appliances
Three phase units deliver more power and run smoothly, making them great for high-demand kitchens. However, they require a compatible electrical system. If your kitchen is mostly hardwired, your equipment may already be three phase. Look for power ratings on the appliance plate, in user manuals, or on the manufacturer’s website.
