MD – Maximum Demand – This is the largest current normally carried within a circuit.

PAT – Portable Applicance Testing. This is the test used to ensure that any portable electrical equipment is fully safe to use.

RCCB – Residual Current Circuit Breaker – These are used to constantly monitor the electricity which is flowing through the live and neutral conductors. It has the ability to immediately disconnect the supply if it
