Abstract

A test system employing a plurality of disconnect devices is provided, wherein each load, such as a lamp, has a local disconnect device that temporarily disconnects the load in order to protect it from high voltage during the test.

Claims

1-16. -16. (canceled)

17. A test system comprising:

a test module and a plurality of disconnect devices, wherein each disconnect device is arranged to selectively disconnect at least one electrical load from wires supplying electricity to at least one electrical load in response to a first disconnect signal in order that the integrity of the wires can be tested, each disconnect device being further arranged to reconnect at least one load in response to a second signal, characterized in that the test module is arranged to check that all disconnect devices have disconnected before commencing a test.

32. A method of testing wiring to lights connected to a power supply via a test system comprising a test module and a plurality of disconnect devices, each disconnect device being arranged to selectively disconnect at least one electrical load from wires supplying electricity to the at least one electrical load in response to a first disconnect signal in order that the integrity of the wires can be tested, each disconnect device being further arranged to reconnect the at least one load in response to a second signal, characterized in that said test module is arranged to check that all disconnect devices have disconnected before commencing a test, the test comprising the steps of:

asserting a disconnect instruction to disconnect the lights;

confirming that all lights have disconnected;

performing at least a test of continuity; and

reconnecting the lights.

33. A method of testing wiring to lights connected to a power supply via a test system comprising a test module and a plurality of disconnect devices, each disconnect device being arranged to selectively disconnect at least one electrical load from wires supplying electricity to the at least one electrical load in response to a first disconnect signal in order that the integrity of the wires can be tested, each disconnect device being further arranged to reconnect the at least one load in response to a second signal, characterized in that said test module is arranged to check that all disconnect devices have disconnected before commencing a test, the test comprising the steps of:

asserting a disconnect instruction to disconnect the lights;

confirming that all lights have disconnected;

performing at least a test of insulation; and

reconnecting the lights.
