STEP 6: ELECTRICAL REQUIREMENTS, CONNECTION & GROUNDING
A 3 or 4 conductor supply may be connected to
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 ground-
ing through the neutral.
The terminal block provided will accept leads with
ring terminals or stripped conductors. A flat
washer and cup washer must be used with
stripped leads. (See Fig. 17).

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 termi-
nal 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.
4 WIRE LEAD CONNECTION
1. Remove top nuts only from the terminal block
studs. Do not remove lower nuts which
secure range internal wiring leads.
2. Remove ground strap screw and bend the strap
up as shown in Fig. 18.
3. Secure the neutral, wire to the center stud of
the terminal block with nut. Tape neutral wire
to strap as shown in Fig 18a.
4. Secure the L1 (black) and L2 (red) power leads
