43 ct shorting terminal block wiring diagram

If you do, then wire it just like the diagram shows with the shorting block between the CT 's and the meter. Connect the CT polarity to one side of the terminal s on the shorting block . Connect the other side to Ia, Ib and Ic on the meter. If you use a 4 terminal block , In will connect to the three "negative" non-polarity wires and ground.

Ct shorting terminal block wiring diagram. current applied. Wiring between the CT s and the power monitor should include a shorting terminal block in the CT secondary circuit. Shorting the secondary with primary current present allows other connect ions to be removed if needed. An open CT secondary with primary current applied produces a hazardous voltage, which On removal of terminal connect ors for current transformer, there is no automatic CT shorting provision. Do not open the secondary of a live CT since dangerous voltage can occur on the terminal connect ors. For safety, secondary of live CT … Academia.edu is a platform for academics to share research papers. Jan 16, 2020 · At left the thermostat wiring diagram illustrates the typical wiring connect ions when installing a Honeywell RTH2300 (or similar) programmable room thermostat. Be sure to identify and label the existing thermostat wires before disconnect ing them from the terminal s on the old thermostat you are replacing.

the secondary of the line CT must be shorted before opening any connect ions to it. For most equipment with ring-terminal connect ions, the threaded terminal block for current transformer termination has automatic CT shorting on removal of the module. Therefore external shorting of the CT s may not be required, the Eaton’s Magnum DS Low-voltage Power Circuit Breakers offer the highest ANSI interrupting and withstand ratings in the industry in the smallest physical size and are the most easily maintained ANSI circuit breakers on the market.

Current Transformers

Open Circuit CT 's. DANGER: Current transformers should remain shorted until connect ed to a secondary circuit. CT s are typically wired to a terminal block where shorting screws can be installed to tie isolated points together. It is important that a CT always have a burden or load connect ed when not in use, otherwise a dangerously high secondary voltage can develop across the secondary terminal s.

It will be easier to connect the wires to the terminal block if the block is first plugged into the meter. Unused CT inputs could possibly pickup elect rical noise, so it is a good pract ice to short out unused CT input terminal s by connect ing a wire jumper about 1 inch long between the white and black CT terminal s.
