Labeled terminal block
The following procedure is used when cables are connected to the terminal block:
•
1/4” of the insulation is carefully stripped from the end of each conductor
•
The terminal screw is loosened
•
The bare portion of the conductor is inserted into the terminal orifice
•
The terminal screw is fastened
The recommended screwdriver is a slot-head type screwdriver suitable for size 0 or size 1
screws (3/32” wide blade). The screws should not be over-tightened as this may damage the
conductor.
