a

DJM circuit breaker has adjustable trip settings from 160–400 A. If required, order seal kit, catalog number 29375. DJM circuit breaker terminal lug kit 32508 factory installed and accomodates (1) 2 AWG–500 kcmil Al or (1) 2 AWG–600 kcmil Cu per phase. Alternate lug kit 32510 for DJM circuit breaker is available, see Accessories, page 2-15. Additional field-installable DB circuit breaker accessories are available, see page 7-35.

b	Supplied with Class 320 lever bypass meter socket. Use anti-inversion clip kit, catalog number MMLRK, if required. Order from page 2-15.

c	DJM circuit breaker alternate lug kit 32510 is available for field installation. See Accessories, page 2-15.

d	For 240/120 Vac Delta Systems add Suffix “CA” to catalog number (Example: EZML312400CA). All meter sockets are phased A and C only. Price remains the same as the base catalog number. “Order only” branch units, not stocked in PDS (4–6 week delivery). Order point Lexington.

 

EZM Main with Busway Tap

EZ Meter-Pak metering equipment is available for use in high rise applications for connection to 800–5000 A I‑Line® or I‑Line II plug-in busway installed as a vertical riser. Three phase only EZM main devices in the form of a main circuit breaker or main fusible switch are available with an integral busway tap extending from the right or left side of the main device and phased to align with the busway for either neutral front or neutral back installations.

Busway Mains, 3Ø only (Indoor only) ordering instructions:

Step 1: Determine height to center line of busway plug-in opening, check local utility requirements for minimum and maximum meter socket heights.

Step 2: Determine side of EZM main section for busway tap to extend from (busway tap is an integral part of the main and extends to the left or right on the EZM device as viewed from the front).

Step 3: Check phasing of busway riser to insure that it matches phasing of busway tap on main section (indicated as neutral front or neutral back as viewed from the front).

Step 4: Select Cat. No. from tables below.

Step 5: Busway main devices are build to order specials and require 4 to 6 weeks for delivery (order point Lexington).
