All APs require power to operate. Provide details in the report about how
and where the APs will tap into the electrical system. APs should be powered
from a 24-hour, input power source breaker. This power source may be shared,
but a dedicated source is preferred.
There are various types and brands
of electrical equipment. An SE does not need to be an expert on these, but
should be able to identify them. This will allow for specific references in the
report when detailing the power source for the AP. For example, the report may
specify that AP 4 will receive power from the Square D box on the north wall of
the shipping area, and that the distance from the electrical box to the AP was
estimated at 44 m (145 ft).
By defining the location and brand of the
breaker box, the electrician will be able to easily identify the box and
install the associated wiring. The SE should also be familiar enough with the
breaker panels to determine if there are available breakers or if the breaker
is full. If a particular box is specified for used and there are no available
breakers, this could present a problem, especially if the report is used to
generate a quote for the electrical work.
Electrical workboxes should be mounted face up so that the weight of the AP
transformer can rest on the faceplate. The transformer should then be secured
to the faceplate or workbox using zip ties.
