TRIPS
NOTE: The CT leads must be stripped approximately 10mm (0.4”) and have a
gauge size between 18 and 26 AWG.
The GEM uses spring loaded terminal blocks. The CT leads must be stripped the
proper length. If the leads have stranded wire, it is preferable to “tin” the wire
beforehand to prevent dealing with frayed ends.
(Tinning is the process of
adding solder to bond all of the strands together) .
The CT leads are inserted into terminal block while pressing down on the
corresponding orange tab (see picture below).
1. Align the two lead ends with the terminal holes. This can be done one lead at a time however it may be easier
inserting both leads at the same time, providing they are tinned with no frayed ends.
2. Press down on the orange TAB(s) corresponding to the lead or leads to be inserted, using a small “flat blade”
screwdriver.
3.
Insert the leads into the terminal block while making sure the leads are perpendicular. In most cases, both CT
leads can be inserted at the same time. If the lead was stripped back 10mm, then the stripped section should be
entirely inside the block with only the insulation visible.
4. Release the pressure to the spring tab.
5. Finally, tug slightly on the leads to make sure they are secure.
