2.Route listed power cord through 7/8-inch diameter hole in J-Box.

3.Secure power cord to J-Box bracket with a strain relief bushing or a connector approved for the type of cord used.

4.Secure field ground wire to green ground screw on J-Box bracket.

5.Connect line voltage leads as shown in Fig. 24.

6.Reinstall cover to J-Box. Do not pinch wires between cover and bracket.

BX. CABLE INSTALLATION IN FURNACE J-BOX

1.Remove cover from J-Box.

2.Route BX cable into 7/8-inch diameter hole in J-Box.

3.Secure BX cable to J-Box bracket with connectors approved for the type of cable used.

4.Secure field ground wire to green ground screw on J-Box bracket.

5.Connect line voltage leads as shown in Fig. 24.

6.Reinstall cover to J-Box. Do not pinch wires between cover and bracket.

24-V WIRING

Make field 24-v connections at the 24-v terminal strip. (See Fig. 34.) Connect terminal Y/Y2 as shown in Fig. 27-33 for proper cooling operation. Use only AWG No. 18, color-coded, copper thermostat wire.

The 24-v circuit contains an automotive-type, 3-amp. fuse located on the control. Any direct shorts during installation, service, or maintenance could cause this fuse to blow. If fuse replacement is required, use ONLY a 3-amp. fuse of identical size.
