Site Transformer, 400:110V, 10 kVA three-phase, continuously rated. 2 x 32A and 4 x 16A sockets individually protected by MCBs and by a common 63A 4P 110V 300mA* Type A RCCB. Also fitted 2 x 10A MCB / 30mA Type A RCDs for direct connection to lighting circuits (3 Core).
*In early 2024 we will start fitting RCCBs with a 100mA sensitivity instead of a 300mA sensitivity. During the transition period you may receive a transformer fitted with an RCCB of either sensitivity.

Distribution
1 no. 63A 4P 110V 300mA* Type A RCCB feeding: 2 no. 32A DP Type “C” MCBs each feeding a 32A 2P+E 110V IP44 socket; and 4 no. 16A DP Type “C” MCBs each feeding a 16A 2P+E 110V IP44 socket. Also fitted 2 no. 10A DP MCB / 30mA Type A RCDs feeding 3 way terminal blocks for direct connection to lighting circuits (the lighting connections can be made without removing the transformer lid). The incorporation of RCD protection ensures compliance with disconnection times on longer lighting circuits with a high Zs.
*In early 2024 we will start fitting RCCBs with a 100mA sensitivity instead of a 300mA sensitivity. During the transition period you may receive a transformer fitted with an RCCB of either sensitivity.
