Worked example

For two example kilns, 2.5 kW and 3.6 kW:

  • 2.5 kW: About 10.9 A, which is within a 13A plug's rating. Only use a plug if the maker's manual says this kiln is a plug-in model.
  • 3.6 kW: About 15.7 A, which is more than a 13A plug can supply. It needs its own circuit (the kind makers list as 16A), fitted by a registered electrician.

Some small kilns come with a plug; bigger ones need their own circuit. Type your kiln's power and this checker works out the current it draws and compares it with a standard plug's rating.

How it works

Current is power divided by voltage. If the current is within a standard plug's rating, the kiln may be a plug-in model. If it's more, it needs its own circuit, and that's a job for a registered electrician.

The kiln's manual always decides. It says whether the kiln comes with a plug or must be hard-wired, and what supply it needs.

FAQs

Can I use an extension lead for a small kiln?

Don't run a high-power machine from an extension lead unless the maker says you can. Plug it straight into a wall socket.

Will you tell me how to wire a kiln in?

No. A new circuit or hard-wired connection must be fitted by a registered electrician. We only say what kind of supply to ask about.
