What is a CT Chamber?

CT (Current Transformer) Chambers are essential components for accurate electricity metering on installations with supplies of 200A and above, typically at 400V TP&N. In these setups, the energy meter operates in conjunction with CTs to enable correct billing based on usage.

CT Chambers are tamper-proof, sealable, and fully insulated enclosures that house the CTs, usually provided by the Distribution Network Operator (DNO) or electricity supplier. Where the DNO does not supply a chamber, it falls to the installer or Building Network Operator (BNO) to provide one.

At Dunore Connections, we supply a range of CT Chambers designed for both permanent and temporary installations, with configurations accepted by a number of major DNOs and BNOs.
