NOTES:
1. Typical ELRs for new installations can be 3.9k or 4.7k ohm.
2. The same gauge wire must be used if two conductors are connected to the same terminal of any terminal block.
3. Do not complete a continuous circuit around the screw terminal. There must be two separate wires on either side of the screw at the
terminal block. “T-tapping” is absolutely NOT ALLOWED.
