ADDITIONAL GROUNDING INFORMATION & SAFETY TIPS
MAJOR CAUSES OF INJURIES AND FATALITIES
• Shocks & electrocution to users from improper use-improper connection to structures, such as
residences, offices, shops and trailers.
SAFE WORK PRACTICES
• Maintain and operate generators in accordance with the manufacturer's use and safety instructions.
• Do not attach a portable generator directly to the electrical system of a structure(home,office or
trailer) unless the generator has a properly installed open-transition transfer switch.
• Always plug electrical appliances and tools directly into the generator using manufacturers supplied
cords. Use heavy duty extension cords that contain a grounding conductor(3-wire flexible cord and
3-pronged cord connectors).
• Proper grounding and bonding prevent shocks and electrocutions.
• Use ground-fault circuit interrupters(GFCIs)as per the manufacturer's instructions.
• Visually inspect the equipment before use; remove defective equipment from service; mark or tag it
as unsafe for use.
GROUNDING REQUIREMENTS(Portable and Vehicle-mounted Generators)
Under the following conditions, OSHA directs that the frame of a portable generator need be grounded
(connected to earth)and that the frame may serve as the ground(in place of the earth):
·The generator supplies only equipment mounted on the generator and/or cord-and plug-connected
equipment through receptacles mounted on the generator.
·The noncurrent-carrying metal parts of equipment(such as the fuel tank, the internal combustion
engine, and the generator's housing)are bonded to the generator frame, and the equipment grounding
conductor terminals are bonded to the generator frame.
Thus, rather than connect to a grounding electrode system, such as a driven ground rod, the generator's
frame replaces the grounding electrode.
If these conditions do not exist, then a grounding electrode, such as a ground rod, is required.
If these conditions do not exist, then a grounding electrode system, such as a driven ground rod, the
generator's frame rep; aces the grounding electrode.
If the portable generator is providing electric to a structure by connection via a transfer switch to a
structure(home,office,shop,trailer,or similar)it must be connected to a grounding electrode system,
such as a driven ground rod. The transfer switch must be approved for the use and installed in
accordance with the manufacturer's installation instructions by a qualified electrician.
SAFE WORK PRACTICES FOR PORTABLE TOOLS
• Do not use underrated cord--replace them with appropriately rated cords that use heavier gauge wires.
• Never use electrical tools or appliances with frayed cords, missing grounding prongs, or damaged or
cracked housings.
• Use double-insulated tools and equipment distinctively marks as such, where possible.
• Use batter-operated tools, where possible.
BONDING VERSUS GROUNDING
Bonding and grounding are separate requirements for generators and other electrical distribution
systems. Grounding means the connection, or the establishment of a connection, of an electric circuit
or equipment to reference ground, which includes the generator's frame. Bonding is the intentional
connection between the grounded circuit conductor(neutral)and the grounding means for the
generator, which includes the generator's frame. Thus, effective bonding of the neutral conductor to
the generator's frame is also a concern for the safe use of the equipment. As with grounding terminal
connections, proper bonding of the neutral terminal of a power receptacle may be confirmed via testing
by a competent electrician with the correct equipment, and the ohmic resistance should measure near
zero and must not be intermittent, which indicates a loose connection.
