  3. 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.

  4. FT Test Switches Consist of (2) components 10 Pole FT Test Switch 10 Pole FT Test Plug

  5. 10 Pole FT Test Switch -- Features & Uses Semi-flush mounted in front panel Rear termination provisions Configurable to meet customer requirements Black or clear (optional) safety cover Provisions for meter type seal Isolate relay inputs & outputs for injection of current & voltage from separate sources (Use “Separate Source” Test Plug) Measure system currents & voltages during field testing & commissioning (Use “In-Service Series” Test Plug) FTC-066 Test Switch with clear cover FT-066 Test Switch with black cover

  7. FT Test Switch – Rear terminals Threaded rear terminals Terminal numbers molded into base Nickel plated brass pan head screws, flats, & locks supplied loose Threaded studs and hex nuts available as option

  8. FT Pole Assemblies “P” = Potential “C-C” Current Shorting (2-Poles Required) “C” = Current Non-Shorting “C-C-C” Current Shorting (3-Poles Required) “C-C-C-C” Current Shorting (4-Poles Required)

  9. 10 Pole FT Test Switch Typical Selection table (Note poles A through J……Reference slide 4) Schematic Symbols “P” = Potential (Poles A, B, & J) “C” = Current Non-Shorting (Pole C) “C-C” = Current Shorting (2-Poles Required) (Poles D-E, F-G, & H-I)

  10. FT Test Switch Potential Pole “P” Non-Shorting Blade used for voltage and trip circuits Rear Termination Provision Blade assembly of (1) position potential pole (P)

  11. FT Current Shorting Pole ‘C-C’ Non-Shorting Blade with Current Test Jack Shorting Blade Bottom cam of the shorting blade makes contact with the shorting spring of the pole to the right before disengaging from the jaw (Make before break contact) Jaw Rear Termination Provision Shorting Spring from Non-Shorting Pole to Right Blade assembly of (2) position current shorting pole with current test jack (C-C) Let’s take a look at the current test jack pole to the right

  12. FT Non-Shorting Current Pole ‘C’ Non-Shorting Blade (Open) Current Test Jack for insertion of current test probe Jaw Rear Termination Provision Blade assembly of non-shorting current pole with current test jack (C) --- Part of 2-pole (C-C)

  13. FT Test Switch Handles Molded slot for circuit identification card Optional interlocking bar kit (3) Potential blades tied together with interlocking bar kit

  16. 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. B C D E F G H I J A B C D E F G H I J A Example: C C- -C R- -R- -R- -R P P P 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. Step 3 Select a cover style Clear (Installs over open or closed switches) Black (Installs over closed switches only) Step 4 Select a rear terminal type Screws (Standard) Studs (Optional)
