Model: Wago CT Extension Pack

 

The eGauge CT Extension Pack can be used to extend CT leads in situations where soldering or butt-splice connections are not possible. CT leads should only be extended using twisted pair wiring and to a maximum recommended distance of 100 feet from the eGauge. 

Prerequisites

Suggested hardware/supplies:

  • eGauge CT Extension Pack (not required, but recommended) Splices may also be soldered.
  • Twisted Pair wire (22 AWG - 18 AWG) or Cat5 using one twisted pair per CT. Extension wire must be twisted pair. 

Important Installation Notes

  • CT leads can be extended up to a maximum recommended distance of 100 feet from the eGauge. Significantly longer distances can affect accuracy.
  • Avoid running CT leads alongside wiring carrying high-voltage to avoid environmental interference.
  • Extension wiring must be twisted pair.

Instructions

If using the Extension Pack, check that you have all included parts:

Qty Item
10 Wago 221-2401 Inline splicing connectors with lever
5 5x Wago 221-2502 Mounting carriers with strain relief

Step 1: Slide the splicing connectors into the mounting carriers by inserting them behind the arrow and gently sliding forward until they click into place.

 

 

Step 2: Remove the 2-pin connector from the CT lead and prep the lead to a strip length of 11mm/0.43". Insert one of the stripped wire ends into one end of an inline splicing connector.

 

 

Step 3: Lift the lever to insert the CT lead and lower the lever to secure the connection. You should use 1 inline connector per lead wire, using 2 inline connectors and 1 carrier to extend a single CT lead.

 

 

Step 4: Strip the ends of the extension wiring to the appropriate length and connect to the other side of the inline splicing connectors in the same way.  Be sure to line up black and white lead wires to the same inline connector.

 

 

Step 5: Attach the green 2-pin CT connector to the other end of the CT extension wiring and plug into the eGauge making sure to keep black and white wiring consistent throughout.  Once assembled, give the wires a light pull to be certain that they're securely seated under the closed levers.

 

 

Troubleshooting and Tips

Question: Can I connect multiple Wagos together?

Answer: Multiple Wago carriers can be connected together if needed using the side-by-side latches on the carriers. The carriers can be mounted or secured as desired.
