Contractually, before restricting power to a customer, the technical teams of both the utility and the customer meet to agree on the restriction modalities to ensure that employees of the mine and its equipment at all times remain safe. A power supply restriction will not take place without the participation of the customer, as such, circuits/loads to be switched off are agreed by both parties.
An all-inclusive power restriction process ensures preservation of the safety of mine equipment and personnel. Restriction means a reduction in the level or amount of power a customer normally receives; it does not mean a complete cutting off of supply. The customer is always left with sufficient power for purposes of safeguarding personnel and the mine’s assets.
