Quick overview

Test Blocks are used during the installation of Current Transformer and/or Voltage Transformer operated meters. 

Testing facilities are required by some Code of Practice applications (click here for more information). They dictate that testing facilities should be available and close to the meter.  The facilities enable the meter to be routinely tested and/or changed safely with the primary supply circuit energised.  The Test Blocks enable just that, the operator can short circuit the CT to either test or change the meter.

We offer test blocks for both single and dual meter installations, please make your selection upon order.
