‹2.1.4 GENERATOR RESTRAINT

Use four 5/16"-18 hardened steel bolts (Grade 5) to fasten the generator to the supporting frame or the support tubing. These bolts must pass through (a) the generator mounting base, (b) the compartment floor (if a compartment is used) and (c) the support- ing framework (Figure 2.3). All bolts must be long enough so that when tight, at least three threads are visible past the retaining lock nuts. Refer to "Generator Compartments" for the location of the generator mounting holes.

Figure 2.3 – Typical Generator Restraint

NOTE:

Refer to “Figure 1.2 – Major Features and Dimensions”.

‹2.2.2 COMPARTMENT CONSTRUCTION

•The generator compartment should be either con- structed of, or lined with, 26-gauge galvanized steel.

NOTE:

Aluminum is NOT an acceptable alternative to galvanized steel due to aluminum’s low melting point.

•If the compartment is lined with galvanized steel, it may be constructed of any material. The manu- facturer recommends that the compartment be constructed of 1/2-inch thick plywood (not strand- board), with the floor made of a double thickness of 1/2-inch plywood with the grain of the wood at cross section for added strength (Figure 2.5).

2.2 GENERATOR COMPARTMENTS

Whether the generator set is being installed inside a compartment specifically manufactured to house a generator or inside a compartment that the installer constructs, the compartment must meet certain spec- ifications as outlined in the following sections:

‹2.2.1 COMPARTMENT SIZE

Plan the compartment size carefully. Provide a mini- mum clearance of 1/2 inch (13 mm) on the front and top, one (1) inch (25 mm) on the sides, and one

(1)inch (25 mm) from the back for air circulation AFTER the compartment has been lined with metal and sound insulation (Figure 2.4).
