Circuit Requirements for Electrical Equipment

How to Determine if your Equipment Requires a Dedicated Electrical Circuit to Prevent Circuit Overload

Dedicated Circuit Requirements for Electrical Equipment
Question: We have a new electric frier for our cafeteria; its 208v/60/3ph, 47.2 amps, 17kw, for direct wiring. I’m told that it should have been ordered in 480v. Can it be safely wired to work by an electrician? Does he have to change the circuits and breakers to provide a safe hook-up?

This electrical question came from: Wayne, a Handyman from Columbus, Ohio.

Thanks for your electrical question Wayne.

Understanding Electrical Circuit Requirements

How to Determine if your Equipment Requires a Dedicated Electrical Circuit to Prevent Circuit Overload

Wayne, the electric frier that you now have requires a dedicated circuit as specified by the nameplate, owners manual and the installation specifications.
From my position I cannot be sure what the voltage is in your cafeteria.
It is essential to know what the voltage is for your facility before the purchase, and realize that equipment such as this will definitely require a dedicated circuit due to the amount of electricity it will require.
Yes, you will need to have a licensed electrical contractor install the necessary circuit for you.
