spaced about 15 feet (4.5m) to 20 feet (6.0m)

apart to limit drooping and avoid contact with

moving parts.

(d) An alternate method is to use the Detector

without messenger wire and fasten the

Detector directly to the angle iron at intervals

of 5 feet (1.5m) to 10 feet (3.0m) with

approved mounting clips.

*The use of messenger wire is optional; how-

ever, when not employed additional fasteners

may be required.

Power Distribution Apparatus

Figure 22 illustrates Protectowire Linear Heat

Detector laced through a motor control panel.

It is secured with PM-3 wire straps to the appa-

ratus being protected. Other equipment that

may be protected in the same manner includes

transformers, switchgear, substations, resistor

banks, etc. where ambient temperatures do

not exceed the Detector’s rating.

Dust Collectors/Baghouses

Figure 23 illustrates Protectowire Linear Heat

Detector, supported by angle brackets,

installed 30 inches (.8m) above the inside

base of a dust collector.

From the base junction box the Detector is

circled around the interior of the outer siding

then run in conduit to the center tube where

the Detector is circled as shown. The Detector

is then run in conduit to the top of the col-

lector where it is supported on messenger

wire in the pattern shown in Figure 23A.

The Detector may also be installed around the

blower motor frames for early detection of an

overheating condition.
