instruction guide is written for such personnel. This

The A. B. Chance Type M3 disconnect switch is a
single-phase hookstick operated switch. It is for
manual switching of de-energized or parallel circuits
of overhead lines on an electrical distribution system.
The M3 switch has no current making or breaking
capacity. Design variations allow for applications as
an electrical distribution switch or as an electrical
station switch. A number of options (connectors,
captive hardware, by-pass studs, etc.) are available
to better fit the user's needs.
The station style M3 disconnect switch is made for
mounting in an inverted (Figure 1) or vertical position
(Figure 2).
Select a properly rated M3 switch for each installation
with consideration to continuous current, BIL, and
rated voltage. Should there be any concern on the use
of this M3 switch as rated, consult your supervisor
before installation.
Inspect the switch for damage or missing parts. If
damage from rough handling is evident, immediately
file a claim with the transportation company. Contact
the nearest Chance sales office for replacement parts.
