◆ 2.1.4 GENERATOR RESTRAINT Figure 2.3 – Typical Compartment Construction

Use four 3/8"-16 hardened steel bolts (Grade 5) to fas- ten the generator to the supporting frame or the sup- port tubing. These bolts must pass through (a) the gen- erator mounting base, (b) the compartment floor (if a compartment is used), and (c) the supporting frame- work (Figure 2.2). All bolts must be long enough so that, when tight, they engage at least 3/8” of an inch [9.5 millimeters]. Refer to Section 2.2 for the location of the generator mounting holes.

2.2GENERATOR 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 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. Generac rec- ommends that the compartment be constructed of 1/2-inch thick plywood (not strandboard), with the floor made of a double thickness of 1/2-inch ply- wood, having the grain of the wood at cross section for added strength (Figure 2.3).

•If constructing a compartment, line the exterior (underside) of the compartment floor with 26- gauge galvanized steel.

•All seams, splices, and joints of the compartment

walls (unless vapor-tight by design) should be caulked to prevent poisonous, flammable, or explosive vapors from entering the vehicle interior.

NOTE:

Caulking must be done so that the caulking mate- rial will stay in place permanently. Pressing mate- rials such as, putty tape, onto joints and seams is NOT acceptable. A high-quality silicone rubber base sealant is recommended.

•Holes and openings made in the compartment walls to allow for the passage of electrical conduit, conductors, hoses, cables, etc., into the vehicle liv- ing area must be sealed vapor-tight with silicone rubber base sealant.

•If a flexible metal conduit is used, it must be sealed internally at the end, where it terminates inside the compartment’s electrical junction box.

NOTE:

Flexible metal conduit, due to its unique con- struction, is NOT vapor-tight along its entire length.
