2.1.4
GENERATOR RESTRAINT
Use four 3/8"-16 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 2.2). All bolts must be long
enough so that, when tight, they engage at least 3/8"
of an inch [9.5 millimeters]. Refer to the "Generator
Compartments" section for the location of the genera-
tor mounting holes.

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 CONSTRUCTION
• The generator compartment should be either con-
structed of, or lined with, 26-gauge galvanized
steel.
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, having the grain of the wood
at cross section for added strength (Figure 2.3).

Recreational Vehicle Generator
Figure 2.3 – Typical Compartment Construction
• If constructing a compartment, line the exterior
(underside) of the compartment floor with 26-
gauge galvanized steel.
• All seams, splices, and joints of the compart-
ment walls (unless vapor-tight by design) should
be caulked to prevent poisonous, flammable, or
explosive vapors from entering the vehicle interior.
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.
Flexible metal conduit, due to its unique construc-
tion, is NOT vapor-tight along its entire length.
