1. On each end, use the tape measure to measure the distance from the center of each
terminal strip ‘zone’ to the point at which the supply power and the high
temperature wire are to be joined.
2. Include additional length to account for wire travel through the knock-out hole and
enough to perform adequate wire stripping prior to attachment to the heater and
power supply wiring.
3. Cut lengths of high temperature wire corresponding to the measured lengths.
4. Strip the insulation from each end of each wire to expose the conductor material
(approximately ½”).
5. Feed the wires into the heater through each end of the heater between the terminal
strip and the back of the heater and up through the knock-out holes.
6. If the amp draw is 50 amps or less, the stripped end of the wire can be inserted
directly into the terminal block. If it is greater than 50 amps, attach a ring lug to the
end of the wire and install the ring onto the bus bar with a screw and nut.
Attach the unconnected end of each high temperature wire to the power supply wiring
using appropriate wire joining techniques (as specified by local electrical codes and
standards).
