The use of screw terminal "chocolate blocks" in building wiring installations has sharply declined in favour of crimp, push and twist type connectors which are not prone to working loose and easier to fit. In the UK chocolate blocks are no longer approved for connections that are not accessible for inspection (ie. under floors).


Power Distribution Terminal Blocks Why use a distribution block? A Distribution block is an economical and convenient way of distributing an electrical circuit from a single input source, to several devices in the branch circuit. Thus re-ducing the total number of wires in your electrical panel and saving you time and money.


A terminal block (also called as connection terminal or terminal connector) is a modular block with an insulated frame that secures two or more wires together. It consists of a clamping component and a conducting strip. A typical simplest terminal block is as shown in the image below.

Once the current transformers are properly shorted using the CT shorting block, it is safe to make wiring modifications on the meter side of the shorting block. Once the intended wiring modifications have been completed, you will need to remove the shorting screws from the positive CT lead terminals in order to return the meter to proper operation.


Catalog # 3090TB4 for 4 pole and 3090TB6 for 6 pole shorting blocks used with CTs. The hazard of electric shock, burn, or explosion exists on an open circuited CT. Death, severe personal injury, or equipment damage can result if the leads are touched when the CT is open-circuited..
