at
is necessary to do is to loop the bottom wire of the circuit down
through the branch moulding, and connect it to the switch at a
terminal block, or porcelain base.

In wiring lamp fixtures, No. 14 rubber-covered wire will usually prove
too large. For this purpose, No. 18 may be used, with one lamp to each
loop. Hanging lamps may not be supported by electric lamp cord itself,
if there is more than one lamp in the cluster, because the weight is
apt to break the electrical connections. In such a case, the lamp
should be supported by a chain, and the twisted cord conveying current
to the electric bulbs, is woven in the links of the chain. For the
pantry, kitchen, woodshed, barn, etc., a single hanging lamp may be
suspended from a fielding rosette, as shown in the cut, provided a
single knot is tied inside both the rosette and the lamp socket, to
make it secure. This makes a very cheap fixture. The rosette of
porcelain will cost 15 cents; the lamp socket 20 cents, and the lamp
cord suspending the lamp and carrying the current will cost 1-1/2
cents a foot; while a tin shade will cost another 15 cents.

_Official Inspection_

In all communities, your insurance agent must inspect and pass your
wiring before you are permitted to throw the main switch and turn on
the electricity. Frequently they require that the moulding be left
uncapped, until they have inspected it. If you have more than 660
watts in lamps to a circuit; if your joints are not soldered and well
taped; if the moulding is used in any concealed or damp place, the
agent is liable to condemn your work and refuse permission to turn on
the electricity. However the rules are so clearly defined that it is
difficult to go wrong; and a farmer who does his own wiring and takes
pride in its appearance is more apt to be right than a professional
electrician who is careless at his task. After the work has been
passed, tack on the moulding capping, with brads, and paint the
moulding to match the woodwork.

Wooden moulding wiring is perfectly satisfactory if properly
installed. It is forbidden in many large cities, because of the
liability of careless workmanship. It should never be installed in
damp places, or out of sight. If the work is well done, the system
leaves nothing to be desired; and it has the additional advantage of
being cheap, and easily done by any farmer who can use carpenter
tools.
