Notice: In cases where a copper conductor is
used, bolt a tinned terminal clamp (if available) to
the aluminum switch terminal pad. If a non-tinned
terminal clamp is used, apply a liberal amount of
electrical joint grease at the joint and all over the
pad of the fitting.
To connect aluminum-to-aluminum terminals:
1. Clean all contact surfaces of conductors and
fittings using a stiff wire brush to remove
heavy oxide coatings until the aluminum
finish is visible and restored.
2. Coat these now clean contact areas with a
liberal amount of corrosion inhibitor such as
NO-OX-ID"A Special" or No. 2 EJC.
3. Abrade the contact surface through the
corrosion inhibitor again using the stiff wire
brush.
Notice: Do not remove the compound.
4. Connect the terminals and torque the bolts as
per Table 1.
To connect copper-to-aluminum terminals:
1. Except for plated surfaces, clean all contact
surfaces of conductors and fittings using a stiff
wire brush to remove heavy oxide coatings
until the aluminum finish is visible and
restored.
2. Prepare any bare copper surfaces in the usual
manner.
3. Coat these now clean contact areas with a
liberal amount of corrosion inhibitor such as
NO-OX-ID "A Special" or no. 2 EJC.
4. Abrade the contact surface through the
corrosion inhibitor using a stiff wire brush.
Notice: Do not remove the electrical joint grease.
5. Connect the terminals and torque the bolts as
per Table 1.
