OPTIONAL ACCESSORY ITEMS
Montgomery Ward carries two types of transfer
switches for use with your MX-27129 standby gener-
ating set. A manual transfer switch (order article no.
89-27134) or an automatic transfer switch (order arti-
cle no. 89-27135) are available to complete your
home standby generating system. The manual
transfer switch kit enables the owner/operator to
switch, up to four possible circuits, to emergency
power during a utility power outage. The total circuit
load requirements must not exceed the nameplate
rating of the MX-27129 emergency power generator
set which is 5000 watts. The manual transfer switch
kit is designed for indoor wall mounting preferably
near the main power distribution panel. The auto-
matic transfer switch is also designed for indoor wall
mounting near the main power distribution panel.
The automatic transfer switch will automatically start
the emergency standby generator set and assume the
load (preselected by the home owner prior to installa-
tion) of the transfer switch. Maximum current rating
of the automatic transfer switch is 30 amperes. Both
switches come with complete installation and operat-
ing instructions.
WARNING
Installation of the manual switch kit and
optional cable kit must be performed by a
qualified licensed electrician and inspected according to all local
and state electrical codes.
