NFPA 110/37 Compliance??
NFPA 110/37 Compliance??
(OP)
Hi there, was wondering whether anyone can help me out with this issue.
We're trying to procure a 60Hz 250kW Caterpillar diesel generator to be used as an essential generator on an onshore oil and gas plant. The client is requesting that the generator complies with NFPA 110/37. We're having difficulties getting a response from the bidders, who are mostly distributors, to say that the engine complies with the 2 standards. We suspect these distributors do not have any prior experience dealing with NFPA standards.
Can anyone (a)tell me whether Caterpillar gen sets comply with these 2 standards, and (b)provide me with a list of reliable distributors of Caterpillar gen sets in the States please? They must have a proven track record in the oil and gas market in the Middle East preferably.
Thanking you in advance.

Having never read either of the Standards mentioned, I would question if the NFPA 37 is intended to apply to reciprocating engine driven generators.
RE: NFPA 110/37 Compliance??
NFPA 37 is a standard for reciprocating and turbine engines. It pertains mostly to the installation.
If your Cat dealer doesn't know these standards (esp. 110), find some place else to buy it.
RE: NFPA 110/37 Compliance??
NFPA 110 specifies the features which are required for a standby system, which is to say that the Standard has specific "Scope", (1-1), and exclusions, (1-1.4), which limit the application of the Standard to the "...installation, maintenance, operation and testing requirements as they pertain to the performance of the emergency power supply system, (EPSS)." The scope is not specific only to "Life Safety" loads, but is applicable to those loads. It interfaces with the "Life Safety Code-NFPA 101" for those provisions. The Standard includes criteria for classification of the EPSS as to Type, (Type U, Type 10, etc...), regarding transfer time, and Class, (Class 0.083, Class 0.25, Class 2,..., (in regards to run without refueling time), and Level, (Level 1 being Life Safety, Level 2-Critical, etc...).
In many cases the basic NFPA provisions are augmented by local requirements, in my case through the California Electrical Code, (which is the NEC with California Amendments).
In any case-back to the original question. Manufacturers cannot manufacture a genset to "meet these standards". They can manufacture equipment which when specified, utilized and installed properly, will meet these standards, but it is up to the person designing the overall system, in this case it sounds like that duty falls to RINEZRY, or his consulting engineer. The manufacturer can provide the equipment but they have no control over those factors which impact the standards referenced, unless they are given a "turnkey" contract, which basically states, "Provide a power plant to delever X megaWatts and meets all provisions of NFPA 37, 99, 101, 110...." or whatever other design criteria are applicable. But you will find, that the manufacturers themselves don't do this,there are power system companies which can, but that's an entirely different animal.
Best of luck with your project. Have a pleasant day.

You really need to be sure to specify 110 compliance when you order the unit.
Would strongly suggest you obtain a copy at
