Standard TDC Series Transformer Distribution Cubicles

Transformer Distribution Cubicles (TDC) are available in wall mounting or floor standing enclosures and combine transformers rated from 2 kVA to 10 kVA with up to 16 no. double-pole outgoing MCBs. Supplying a factory built, composite, transformer distribution cubicle reduces on-site installation time and results in a more consistent installation. Standard TDCs are fitted with a 300mA 110V RCD on the secondary, to ensure compliance with BS7671 Regulation 411.8.3, which specifies a 5 second disconnection time for RLV circuits.
