The member shall designate the point of delivery where the member desires to receive electric energy and shall provide service entrance conductors and any material or equipment needed for the receipt of electric energy. What is the difference between voltage and current? Both of them are known as instrument transformers and are mainly used for measurement purposes such as electrical current flow and system voltage. Equipment and wiring must have adequate load and fault ratings. s r s r)](=JOSTx*=JOSTxVY As always remember that there is no standard on colors in the metering field.

Please note this does not cover high voltage metering. For the form 4s meter wiring diagram lets start at the bottom. startxref 0000014108 00000 n How to wire meter for single part supply? Now there are some odd 480v services out there that use this service so be aware. Here, you can see the connection diagram of CT and PT for a Three-Phase system where three live wires and a neutral wire are available. m,)L. We have two phase wires and a neutral. A 240 volt meter is used for 277/480V service. 0000052635 00000 n *fb~SVftL%V{~)rET1ecK]l*Y Terms of Use And all information provided in this blog is for general knowledge only.
