Installer Instructions

WARNING: Failure to follow these instructions could

result in death, personal injury, or property damage.

• This circuit breaker is intended for use on either

single-phase grounded 120Vac 2-wire branch circuits

or on 120/240Vac or 120/208Vac shared neutral

circuits where the neutral from separate branch

circuits is combined to one neutral wire and returned

to either breaker.

• A handle tie is required for 2 or 3 single pole non

common trip breakers on shared neutral circuits. See

wiring diagram below and download DET-719 from

electrification.us.abb.com for additional information.

• This equipment must be installed and serviced only

by a qualified electrician.

WARNING: Turn off power to main breaker before

beginning installation. Failure to do so will risk

electrical shock and possible death, personal injury,

or property damage.

Installation Instructions
Install the AFCI using the following procedure:

1. Open the AFCI by moving its handle firmly to the

OFF position.

2. Install the AFCI into the load center by plugging

or bolting the circuit breaker into the desired

circuit position.

3. Connect the coiled white “pigtail” wire from the AFCI

to the panel or enclosure neutral bus terminal and

secure it tightly. Uncoil pigtail as necessary (see

connection diagram)

4. Connect the white (neutral) load wire to the terminal

side of the circuit breaker, identified by a silver-

colored terminal screw, labeled LOAD NEUTRAL

5. Connect black (hot) wire to circuit breaker terminals

labeled LOAD, identified by a gold-colored terminal

screw.

6. Turn on power, then close and test the AFCI using the

test rocker switch on the front of the breaker. Follow

the Test Procedure indicated in the next section.

7. See Troubleshooting Guides on the next page on how

to troubleshoot an AFCI.

WARNING: Do not reverse-feed or back-wire. Do not

subject to megger, high-voltage, or high-pot tests.

Remove the circuit breaker before high-potting occurs

on the circuit or the system.

NOTE: The neutral pigtail on eMCB’s (AFCI, GFCI and

DFCI) can be cut to length in the field or extended

using approved connectors. Additionally, eMCB’s with

shortened neutrals can be installed as shown

providing a fast and clean installation.
