This is the typical installation method for electricalequipment in almost every country in the world.

This type of installation will limit the ability of the fire suppression system to work in adverse conditions and increase liability to the insurer.

It is important to design the electrical system from a fireprotection viewpoint, rather than exclusively electrical safety.

Remember the circuit breaker, the service entrance rating and the Short Circuit Current Rating?

Starting Methods

36

Choosing Starting MethodChoosing Starting MethodChoosing Starting MethodChoosing Starting Method

What impact does the motor starting method have on the electrical system?

– The starting method provides control of the current inrush (Amperage) during motor starting.

– The current inrush (amperage) created by the motor reaches it’s peak during motor starting. This high amperage load causes incoming voltage to drop.

– Amperage Load Example - Full Voltage Starting

100HP Fire Pump Motor operating at 380 volts

Full Load Amperage = 165 Amps

Across the Line Starting Amps = 6 x 165 = 990 Amps

Since these devices are life safety equipment they must be very reliable

In general, electrical distribution systems emphasis is on the protection of conductors and or devices

– With fire pump controllers the emphasis is on operation even to the point of sacrificing the equipment

shipment, storage, or installation.

Controller out of sight line with pump.

Auxiliary loads such as jockey pump, lighting and heating circuits cannot be connected anywhere inside of the controller’s enclosure.

– Controller mounted on a flammable surface.

– Controller located such that breaking or leaking pipes could damage the controller.

Voltage IncompatibilityVoltage IncompatibilityVoltage IncompatibilityVoltage Incompatibility Job Site Voltage is Different Than That Specified on the Customer

Order.

– Usually discovered very late at the job site, well after the controller has shipped.

– Installing personnel may attempt to change controller voltage by reconfiguring the control circuit transformer.

NFPA 20 requires the contactor coil voltage to be the same as line voltage. Damage to the controller will result if incorrect voltage is applied to the controller.


159159

Protective Service DevicesProtective Service DevicesProtective Service DevicesProtective Service Devices

Electrical feeder circuit protective devices (circuit breakers or fused disconnects) are required by NFPA20 to be sized at 6 times full load amps (locked rotor amps) plus the full load amps of all connected devices.

These devices are required to be monitored.

NFPA 20 and NEC 70 do not require these devices, some local AHJ’s do.


160160

Field WiringField WiringField WiringField Wiring Wire Size Too Large

– Wire Size that is too large to fit into the controller’s LINE terminals.

– Usually caused by the electrical designer or installing personnel selecting wire size based on 6 times full load amperage rating of service protective devices.

– Lug (terminal) sized based on 125% of full load amps (FLA).

Wire Size Too Small

– Some installations with long distance between service transformer and controller will require wire larger than 125% to accommodate line loss.

– Code allows for a junction box electrically upstream of the controller where wire size reduction can be accomplished.

– Reductions inside the controller constitute a junction.


161161

Field WiringField WiringField WiringField Wiring

Field electrical connections at the controller LINE and LOAD terminals are found mechanically loose or inadequately torqued, posing a potential safety hazard.

Mechanically loose terminations in motor conduit box.

Service wiring not in approved conduit or of sufficient fire rating.

– Conduit must be rigid, liquid tight flexible or type MI cable with 1 hour fire rating.

– Pump room and electrical switching room exempt from fire rating.


162162

Electric Motor WiringElectric Motor WiringElectric Motor WiringElectric Motor Wiring


Motor Winding Connections Incorrectly Field Connected for Correct Line Service Voltage

Motor Winding Connections Incorrectly Field Connected for Type of Starting – Full Voltage or Reduced Voltage Type

Insufficient Wiring Run Between a Reduced Voltage Controller and Motor (For Example: Wye Delta Requires Six Motor Leads)

– Frequently, electrical plans show three phases which installing personnel interpret as three wires.

– Similarly, some electrical plans are one line diagrams and do not detail the wiring between motor and controller.

Inadequate insulation materials on field wiring at lead terminations in motor conduit box. Presents the chance for phase to phase or phase to ground short circuit.
