In our general physics course for non-science students, we have for some years given the students a chance to "experiment" with electrical equipment usually found in the home, and to make it more real, we have arranged a panel to simulate a house with the main entrance switch, fuse block, kilowatt-hour meter, and two branch fuse blocks; one going to an ordinary group of switches and outlets, and the other to a lamp to be controlled by two three-way switches. Regular commercial fixtures, switches, flush receptacles, etc., are used throughout. The student is given a pair of pliers, screwdriver, roll of tape, etc., following a lecture on safety precautions such as tight connections, soldered joints, conduit, etc. The wiring is then done by the students and in so far as time permits, they are allowed to use the trial and error method as the circuit is well protected by fuses.
