What electrical circuit protection is required for the T80 Easi Fit?

A 40A Miniature Circuit Breaker (MCB) or a 45A cartridge fuse is required for both the 8.5kW and 9.5kW models. A 30mA residual current device (RCD) must also be installed in the shower circuit, either as part of the consumer unit or as a separate unit. Additionally, a 45A double pole isolating switch with a minimum contact gap of 3mm in both poles must be incorporated in the circuit. (Pages 5, 4)
