The Installation Acceptance found in NFPA 110, 2005 edition, chapter 7.13 is perhaps the most neglected provision of the building code. It is required by every jurisdiction that requires code compliance. This provision is found in the very first NFPA 110 as well in the latest edition, yet it is constantly ignored. It shouldn't be. It is brilliant.
The generator industry builds excellent products, but their goal is primarily return on investment. As a result marketing plays a dominating role in their business plan. NFPA 110 is the leading tool the owner has to defend against marketing. NFPA 110 is intended to protect the public and make sure the owner gets what he paid for. The Installation Acceptance test is culmination of the writers's efforts.
When the appropriate time for the Installation Acceptance test comes, all of the standby generator equipment will be required to work together for the first time. The radiator works with the duct work for the first time. The automatic transfer switch works with the generator for the first time. The load including fire pumps and smoke control fans work with the generator for the first time. The fuel delivery system supports the engine for the first time, and so on.
The Installation Acceptance test from NFPA 110 is essential to make sure the system will function together properly during an emergency to come.
