Engineers inspect a large circuit breaker before running a night-time short circuit test in one of the five test cells of the General Electric Company's new High-Capacity Switchgear Testing Laboratory in Philadelphia, PA. Observer in shock-proof dugout (foreground) will watch the test at close range. Signal lights (right background) flash "red" to warn that test is about to start. If the fuses in three-quarter million homes were to blow simultaneously, the total short-circuit kva interrupter would be less than can be produced into a single test in the new laboratory.
