STEP 6: ELECTRICAL REQUIREMENTS, CONNECTION & GROUNDING

the terminal block. A 4 conductor supply shall
be used only when the range is installed in a
mobile home or where local codes do not
permit grounding through the neutral.
3 WIRE LEAD CONNECTION
1. Remove upper nuts only from the terminal
block studs. Do not remove nuts which
secure range internal wiring leads.
2. Secure the neutral, grounded wire of the
supply circuit, to the center stud of the
terminal block with nut. (See Fig. 17a).
3. Secure the L1 (black) and L2 (red) power leads
to the outside terminal block studs (brass
colored) with nuts.
4. Tighten nuts securely.

block studs. Do not remove lower nuts
which secure range internal wiring
leads.

the terminal block with nut. Tape neutral
wire and connector, as shown in Fig. 18a to

leads to the outside terminal studs (brass
colored) with nuts.
