WIRING
wiring runs in heated zones. When ambient temperature in
heated zone exceeds that for which insulated wire is recom-
mended use bare nickel-plated copper with porcelain beads,
tubing or buss bar. Consult local Chromalox representative.
4. Users should install adequate back-up controls and safety
devices with their electric heating equipment. Selection of
controls, thermostat, SCR units, contactors and etc. depends
on the degree of accuracy required, reliability, electrical rating
of heater and economic considerations.
WARNING: Hazard of Electric Shock. Any installation
involving electric heaters must be effectively ground-
ed in accordance with the National Electrical Code to
eliminate shock hazard.
1. All wiring should be done in accordance with the National
Electrical Code and with local codes by a qualified person.
2. Connect air heaters to same line voltage, phase and frequency
as on heater nameplate.
3. Teflon insulated nickel plated copper wire or buss bar is rec-
5. Below is an example of standard CAB 122 480V 3P 12 kW
ommended for power connections to heater terminals and for
wired with recommended back-up controls (Figure 3).
