Is vehicle impact protection required by code for permanent standby generators?

Installed where? Parking lot or deserted island?

If I was asking about vehicle impact it was more than likely a parking lot.

The only thing I can find is this.
110.26(E)(2) Outdoor. Outdoor electrical equipment shall be installed
in suitable enclosures and shall be protected from
accidental contact by unauthorized personnel, or by vehicular
traffic, or by accidental spillage or leakage from piping systems.
The working clearance space shall include thezone described in 110.26(A).
No architectural appurtenance
or other equipment shall be located in this zone.

Or if it is over 600v.
110.32(D) Enclosed Equipment Accessible to Unqualified Persons.
Ventilating or similar openings in equipment shall be
designed such that foreign objects inserted through these
openings are deflected from energized parts. Where exposed
to physical damage from vehicular traffic, suitable
guards shall be provided

The last generator I set we had to install them, but it was a code for the fire dept. Because of
The amount of diesel fuel stored.

Vehicle impact protection would also need to consider what size and type of vehicle is expected to be present to cause damage as well as how fast it may be traveling.
Protection from passenger cars at a parking lot likely will not need to be same as protection at a distribution warehouse/yard where there is big trucks, forklifts, or other material handling equipment.

Don't 'overthink' this.
How to make a bollard? Well, a quick resource is the requirements of your local PoCo. They will typically specify, in great detail, bollard construction for transformer pads, etc.
As I figure it, the PoCo has had some experience with 'typical' vehicle impacts. Please also note that it IS allowed to have the protection block access to the equipment, as long as the offending parts can be removed when service is necessary.
A typical bollard is made of 4-6" "well casing," is set into 3ft. of concrete, and extends 3-4ft. above the surface. The pipe is filled with concrete and the top is shaped to drain.
"Well casing" is made of a pretty hard steel alloy, and is best cut with an angle grinder, using a slitting blade. Band saw blades tend to just polish the rust on the side of the pipe. In practice, this means it can be really hard to set the poles so that the tops are all even with each other.
Yellow has to be the worst color to paint. Expect to apply at least six coats before you get that nice, uniform finish. Priming is recommended, and an oil-based paint (like Rust-Oleum) is preferred. If you wrap the roller in a plastic bag, you can use it to apply the next coat. One of those 4" 'regular' rollers (not the little foam gizmos) works well.

Here are the requirements listed in the IBC
1607.7.3 Vehicle barrier systems. Vehicle barrier systems for passenger vehicles shall be designed to resist a single load of 6,000 pounds (26.70 kN) applied horizontally in any direction to the barrier system and shall have anchorage or attachment capable of transmitting this load to the structure. For design of the system, two loading conditions shall be analyzed. The first condition shall apply the load at a height of 1 foot, 6 inches (457 mm) above the floor or ramp surface. The second loading condition shall apply the load at 2 feet, 3 inches (686 mm) above the floor or ramp surface. The more severe load condition shall govern the design of the barrier restraint system. The load shall be assumed to act on an area not to exceed 1 square foot (0.0929 m2), and is not required to be assumed to act concurrently with any handrail or guard loadings specified in Section 1607.7.1. Garages accommodating trucks and buses shall be designed in accordance with an approved method that contains provisions for traffic railings.

Who on earth is going to do a force calculation? How would you test it?
Here, by comparison, is the specification from one PoCo: http://www.nvenergy.com/business/ne...ectric_standards/images/SECTION_6/PE0009U.pdf
I'll bet those work.
