Always check with your venue the number of circuits that can be used for catering equipment. Not all halls or homes can manage multiple heating appliances working at the same time without overloading the circuits.  When this happens, it will stop the unit heating and can cause damage to the unit.

Each unit must be plugged into one power point only, even if there is a double power point.

You should use only one power point for each heating unit per circuit.

To ensure a stress free function, it is always recommended to have a trial run of the heating appliances working together, prior to start time.
