Part 3 — Electric Test for Fixtures

A very useful device for testing out fixtures before they are connected up can be easily made as follows: Two wires are run from a plug, A, one to a socket, B, and the other to terminate at C. The line from the other side of the socket B terminates at D.

In testing a fixture, the plug A is turned into a socket of some source of current, and a lamp is turned into the socket B. The terminal C is held to the metal covering of the fixture, while the end D is held to one of the wires. If there is a leak of current, the lamp at B and those of the fixture will light up.—Contributed by Fred Schumacher, Brooklyn, N. Y.
