Understanding the Difference Between 10 Amp, 15 Amp, Single Phase & Three Phase Power for Electric Equipment

When buying electric commercial kitchen equipment, you’ll often see terms like 10 amp, 15 amp, single phase, and three phase. If you’re not an electrician, these specs might seem confusing—but they directly impact how your appliance performs, how it’s installed, and what kind of plug it needs.

In this guide, we’ll break it all down so you can confidently choose the right appliance for your setup.

What Does “Amp” Mean?

An amp (ampere) is a unit of electrical current. The higher the amp rating, the more electricity the appliance draws. Most commercial kitchen appliances fall into one of these categories:

• 10 amp – Standard power (like a home appliance)
• 15 amp – Higher power, but still single phase
• 20+ amp / Three phase – Heavy-duty, industrial-grade power

10 Amp vs 15 Amp – What’s the Difference?

10 Amp Appliances

• Common in household and light commercial use
• Uses a standard power point (like a toaster or microwave)
• Plug: Two flat pins + one earth pin (same size)
• Max power draw: Approx. 2,400 watts

Best For:

Small benchtop appliances (e.g., mixers, blenders, small toasters)

15 Amp Appliances

• Draws more power for higher-performance equipment
• Requires a dedicated 15 amp outlet
• Plug: Slightly larger earth pin than 10 amp plugs
• Max power draw: Approx. 3,600 watts

Best For:

Commercial fryers, convection ovens, larger dishwashers, combi steamers (light duty)

Note: You can’t plug a 15 amp appliance into a 10 amp outlet—the pins won’t fit.

What Is “Single Phase” Power?

Single phase power is the most common electrical supply for homes and small businesses. It delivers power through two wires: active and neutral. Most 10 amp and 15 amp appliances run on single phase.

• Easy to install and maintain
• Typically enough for low to medium-load appliances
• Available in both 240V/10A and 240V/15A formats

What Is “Three Phase” Power?

Three phase power is used in commercial and industrial settings for high-powered equipment. It delivers electricity in three alternating currents, allowing machines to run more efficiently with greater stability.

• More power, smoother performance
• Reduces energy loss over time
• Required for large ovens, combi ovens, industrial mixers, heavy-duty fryers

Plug Type:

Usually features a round, five-pin plug and requires installation by a licensed electrician.

Choosing between 10 amp, 15 amp, single phase, and three phase comes down to what your equipment needs, how much power your kitchen can support, and what kind of performance you expect.
