INTRODUCTION
This bulletin contains instructions for installing and wiring an Emergency Lighting Control Panelboard
(ELCPB). The ELCPB is specifically designed to contain UL924 listed Automatic Load Control Relays
(ALCR) for use with emergency lighting control in accordance with NEC.
The ELCPB breaker section is connected to the emergency feed from a transfer switch. The ELCPB
ALCR sections provide power through its relay contact and controls egress lighting. Regular panelboard
power is used by the ELCPB ALCRs for monitoring a building's voltage.
The design of the ALCRs and the ELCPB maintains isolation between emergency and regular building
power. When a building's power is in a regular power state, the egress lighting is turned ON and OFF
with the regular lighting in the facility. In an emergency state the ELCPB controlling the egress lighting
is automatically switched ON and waiting for back-up power from a generator or emergency source.

This unit has more than one power supply connection point. To reduce the risk of electric shock,
disconnect the branch circuit breakers or fuses and the emergency power supplies before servicing
this unit.
Turn off all electrical power supplying this equipment before working on or inside the equipment.
Always use a properly rated voltage sensing device to confirm that power is off.
Replace all devices, doors, and covers before turning on power to this equipment.
Failure to follow these instructions will result in death or serious injury.
ENCLOSURE AND INTERIOR MOUNTING FOR THE ELCPB
A separate standards publication, titled “General Instructions for Proper Installation, Operation, and
Maintenance of Panelboards Rated 600 Volts or Less” (NEMA PB1.1), has been provided with this
equipment. Familiarize yourself with the content of this document before proceeding with any of the
following procedures.
If you did not receive a copy of this document, or if you have any questions regarding this equipment,
