3 3 GE Digital Energy Instrument Transformers, Inc. What are Test Switches & Test Plugs? Test Switches are devices designed for mounting on switchboard panels for use in conjunction with proper test equipment to facilitate the testing of instruments, meters, and relays. Test Plugs are multi circuit devices designed to be used with test switches to enable easy measurement, calibration, verification or maintenance of instruments, meters, and relays.

16 16 GE Digital Energy Instrument Transformers, Inc. Non-Standard FT Test Switch Specification Form Step 1 The switch body can support 1 to 10 poles in slots marked A through J. Enter a letter from the legend. Leave unused slots blank. Legend: P = Potential, Black; T = Potential, Red; O = Potential, Orange; Y = Potential, Yellow; G = Potential, Green; B = Potential, Blue; W = Potential, White C = Current, Non-shorting, Black R = Current, Non-shorting, Red C--C, C--C--C, C--C--C--C = Current, Shorting with current test jack right most position, Black R--R, R--R--R, R--R--R--R = Current, Shorting with current test jack right most position, Red CO = Current, Orange; CY = Current, Yellow;CG = Current, Green; CB = Current, Blue; CW = Current, White Note: Some functions will require more than one slot in the switch body Step 2 If a tie bar is required check this box and draw a dark heavy line over the poles to be joined. In the example above positions H, I, & J will operate together.
