_Electric Wiring Principles._--Public utilities are organized to furnish
electric service and it will be found that they are ready to assist
customers in securing the most satisfactory use of electricity. Such
knowledge, based on experience, will be valuable in helping owners to
avoid costly mistakes and to provide for a wiring system that will be
economical and yet complete. When the plans and specifications of the
wiring system have been worked out, it is important to secure bids from
reliable contractors. Only those contractors who can do the work in a
capable manner should be employed and it should be determined in advance
that the installation will be in strict compliance with the National
Electrical Code. For wiring work it is necessary to know the number of
amperes the wire is to carry. This may be determined by dividing the load
in watts by the voltage which is to be used.
The service lateral is a system of wires which form a path over which
electricity is carried from the main line to the house. This is generally
built by the utility company and its cost will depend upon the distance of
the residence from the main line and whether the owner furnishes poles,
labor, etc.
Wires should be of such size as to give sufficient mechanical strength to
stand up under sleet conditions. Usually three entrance wires are used to
carry the electric energy from the utility connection to the house. The
lateral is the electrical doorway to the farm and is the most essential
part of the wiring system. The wires should be of adequate size so as to
provide proper voltage and give complete electrical service for all
ordinary requirements of current.
It is important to see that the electrical equipment is properly
"grounded," that is, the connecting to earth of certain metallic objects
which are near power conductors. The purpose is to carry to the earth any
heavy electrical charge which might exist on such objects and cause
electrical shocks when they are touched. Grounding may be secured by
connecting with water pipes that reach some depth under ground, or driven
pipe may be used as a means of securing intimate contact with moist earth.
