Our EZM busway tap devices have been designed with space savings in mind so that they not only meet challenging job requirements, but the compact footprint also makes them easier to handle and install. EZ Meter-Pak™ test block bypass meter-breaker units, which attach to a main device, are available in configurations providing one, two or three meter socket positions. All units are UL listed for either indoor or outdoor applications. For new installations, the EZ Meter-Pak™ test block meter-breaker units can be used with any EUSERC designed EZM main device, including circuit breakers, fusible switches or terminal boxes. The units can also be added to an existing EZ Meter-Pak™ line.
