Warning
Always connect the wires to the LAN equipment first before you
connect the wires to the circuit breaker. Do not work with HOT feeds
to avoid the danger of physical injury from electrical shock. Always
be sure that the circuit breaker is in the OFF position before
connecting the wires to the breaker.
