Electrical connections:
All wiring must be in accordance with
Article 760 of NEC or the local building
codes.
Some signal is lost in the zone wires
due to line resistance. Refer to the
tables below to determine the decibel
loss for various wire gauges and
lengths. A reduction in load reduces
the loss. Use the largest wire size
possible for the smallest loss.
