Olson, Gary L.

Since there is no basis of evaluation in the proposed new text, it may be assumed that the criteria for approval is decided by the NRTL. Thiscannot result in an approval that will provide consistent, positive results and is likely to result in even a worse situation. Manufacturers willhave no way to know whether the hardware they provide will be approved, and will be held responsible for whatever requirements arearbitrarily selected. Facility owners and equipment suppliers may be exposed to considerable delays and cost increases. So, the proposedchange does not solve the problem raised in the request for change.

5.6.3.6.1

A battery charger driven by the prime mover shall not be required for Level 2 generators , provided the automatic battery chargerhas a high-low rate capable of fully charging the starting battery during running conditions as specified in 5.6.3.6 within the timeframe required by this standard while powering all loads connected to the starting batteries .

Committee Statement

CommitteeStatement:

An AC powered battery charger is less reliable than a mechanically driven DC alternator because the AC-powered systemhas several single points of failure including the incremental wiring, ac protective devices, and the charger itself. So, for criticalapplications it is reasonable to require both DC power sources in the system.

Generators often have significant DC loads when they are operating, in addition to the starting battery recharge duty. Thisaddition makes it clear that the charger for critical applications must be capable of continuous operation with all loadsattached.

First Revision No. 7-NFPA 110-2016 [ Section No. 5.6.4.7 ]

5.6.4.7

All chargers shall include the following characteristics, which are to be accomplished without manual intervention (i.e., manual switchor manual tap changing):

(1) At its rated voltage, the charger shall be capable of delivering energy into a fully discharged battery unit without damaging thebattery.

(2) The charger shall be capable of returning the fully discharged battery to 100 percent of its ampere-hour rating within the timespecified in Table 5.6.4.2, item (f).

(3) As specified in Table 5.6.4.2, item (e), meters with an accuracy within 5 percent of range shall be furnished.

(4) The generator set or charger shall be permanently marked with the following:

(a) Allowable range of battery unit capacity that can be recharged within the time requirements of Table 5.6.4.2

(b) Nominal output current and voltage

(c) Sufficient battery-type data to allow replacement batteries to be obtained

(5) The battery charger output and performance shall be compatible with the batteries furnished.

(6) Battery chargers used in Level 1 systems shall include temperature compensation for charge rate.




Street Address:

Committee Statement

CommitteeStatement:

The marking requirements in (4)(a), (b), and (c) are modified to make the requirement more clear.

Temperature compensation is added because battery failure is the most common reason for failure of a generator set to startand pick up loads. Improper charge rate is the most common reason for premature battery failure because proper charge rateis temperature dependent, and without temperature compensation there isn't a good way to assure that a proper charge rate isachieved.

This does not say that the mechanical switch needs to be used to initiate a test. Only that one must be included in the control panel.


Hunt, James

"mechanical switch" is too restrictive. some manufacturers may want to perform switching functions as part of a more integrated controlpanel. Possibly in the form of a touch screen or other method. As long as safety and functionality is maintained, the operation mode is notimportant.

Olson, Gary L.

The use of the term "mechanical" may be interpreted as being limited to, for example, a rotary switch with mechanical contacts to signalcontrol operation, which is really not the most reliable means of manually entering information into a control panel. I would suggest replacingthe word "mechanical" with "operator mode select" switch, which would allow for use of a wide range of switches without risk of improperinterpretation.

Windey, Timothy P.

The intent of the submitters PI was to make this more flexible, as modern digital generator controls have HMI membrane panels that includethe switch function. The intent was not to insert the word "mechanical" ahead of the word "switch".

Remote start circuits for most generator sets will accept either a N.O. or a N.C. contact, so the requirement shouldn't be tiedto just the N.O. case. For example, a NC remote contact must be used when projects require fail-safe genset start/stopwiring.

It should also be noted that Fire Pump ATS start signals for a generator set are required to be "fail-safe", so the requirement for contactclosure to start would conflict with that requirement.

Windey, Timothy P.

I am the submitter of PI 49. This was handled correctly when it came up in the meeting, but the report got the wording wrong. Please correctthe wording, so it is per the outcome in the panel meeting.

The emergency stop switch should not be mandated to be tamper proof here in 110. That should be left up to the AHJ depending on theinstallation. The emergency stop switch could be located inside an area that is already secured/ tamper proof.

Olson, Gary L.

The change is unnecessary, since the NEC in article 445.18 (B)(2) now covers this requirement.

5.6.9.9

The generator instrument panel for Level 1 applications shall contain the following:

(1) An ac voltmeter(s) for each phase or a phase selector switch

(2) An ac ammeter(s) for each phase or a phase selector switch

(3) A frequency meter

(4) A voltage-adjusting feature to allow ± 5 percent voltage adjustment

(5) An ac kW meter indicating total load on the generator set

Committee Statement

CommitteeStatement:

In a generator set application an engine has very limited overload capability, and without a kW meter there is no easy way foran operator to visually see when loads are approaching the limits of the engine. Because ammeters don't consider powerfactor, they don't actually indicate impending overload on an engine.

Level 1 systems should have this critical feature. kW meters are now a standard feature in most generator set products usedin Level 1 systems.

First Revision No. 16-NFPA 110-2016 [ Section No. 6.3 ]

6.3 Load Switching (Load Shedding). Requirements for Paralleled Generator Sets.

When two or more engine generator sets are paralleled for emergency power, the paralleled system is the source, and system logicshall be arranged to inhibit connection of EPS-damaging loads manage the loads to maintain power quality .

6.3.1

Each transfer switch shall have a continuous current rating and interrupting rating for all classes of loads to be served.

6.3.2

The transfer switch shall be capable of withstanding the available fault current at the point of installation.

6.3.1

The transfer of loads to the EPS shall be sequenced as follows:

(1) First-priority loads shall be switched to the emergency bus upon sensing the availability of emergency power on the bus.

(2) Each time an additional engine generator set is connected to the bus, a remaining load shall be connected in order of priorityuntil all emergency loads are connected to the bus.

(3) The system shall be designed so that, upon failure of one or more engine generator sets, the load is automatically reduced,starting with the load of least priority and proceeding in ascending priority, so that the last load affected is the highest-priorityload.

Committee Statement

CommitteeStatement:

The title "Load Switching (Load Shedding)" was too specific and only described 6.3.3.(3). Section 6.3 and the underlying textare about the requirements for transfer switches used with paralleled generator sets. The last part of the sentence was changedto clarify that the system logic is managing the loads, whether it's priority pickup (when gensets are coming on line), or loadshed (if a genset fails). This revision also clarifies that the paralleled system is the source, so that ATS ratings can be correctlychosen.

The requirements in 6.3.1 and 6.3.2 are deleted since they are already covered 6.1.4 and 6.1.5.

Committee Statement

CommitteeStatement:

Load level on natural gas generator sets can be qualified in the same way that they are for diesel generator sets, with theprimary difference being that the required exhaust gas temperature level is different, and it takes considerably less load toreach that temperature. Separate paragraphs for diesel and natural gas generator sets are not needed.

Preventing damage/degradation in the engine is not the only concern with generator sets: operating them at load helps to drivemoisture out of the electrical portions of the system so they are less likely to fail. So, even if the gas genset may run a fewmore hours a year than might be allowed with the current rules, the effect on the generator is beneficial.

A.5.1.1(1)

The grade of diesel fuel selected for use in a prime mover should be based on recommendations from the diesel enginemanufacturer and ASTM D975, Standard Specification for Diesel Fuel Oils. Where possible, the The purchaser of fuel for the primemover should specify a diesel fuel that does not contain biodiesel, which can accelerate the degradation of the diesel fuel if storedlonger than 6 months. If diesel fuel is stored outside for long-term storage, it can be necessary to use a winter or arctic grade ofdiesel fuel or to take precautions such as insulating and heat-tracing fuel tanks and lines to ensure that fuel will flow to the primemover under the coldest possible conditions.

ATSs can be provided with accessory controls that provide a signal to operate remote motor controls that disconnect motors prior totransfer and to reconnect them after transfer when the residual voltage has been substantially reduced. Another method is to providein-phase monitors within the ATS in order to prevent retransfer to the primary source until both sources are nearly synchronized. Athird method is to use a programmed neutral position transfer switch. See Section 230.95 of NFPA 70 , National Electrical Code .
