Heavy Duty Metered supplies are generally used for commercial and industrial customers where their load exceeds 50kVA.

Our preferred Heavy Duty metering arrangement is shown on drawing M145.

M33 and M33A drawings are used where the Heavy Duty supply is terminated directly in to a customer provided LV switch board.

We will advise you on the correct type of Heavy Duty supply arrangement to fit your particular project.

Please complete an Electricity Network Enquiry Form.
