MTC 6003 ECKv

Roam's MTC® 6003 ECKv series ("v" = Voltage Code) of Generator Interface Panels (Generator Connection Boxes) provide a compact, rugged, and cost-effective exterior connection point for emergency power. These Generator Interface Panels use E1016 (J-Series/16 Series) Male Cam-Lok* brand connectors and are part of Roam's UL Listed (US & Canada) series of three-phase generator interface panels.

The standard in safety and outdoor reliability, Roam's line of Generator Interface Boxes makes connecting a portable generator to your site fast, easy, and most importantly—safe. Generator Interface Panels like those made by Roam are also known in various industries under other names such as Generator Connector Panels, Tap Boxes, Inlet Boxes, Docking Stations, Generator Plugs, Gen Boxes, and Generator Quick Connects. Roam uses genuine Cooper Crouse-Hinds Cam-Lok brand connectors. Similar compatible connectors are sometimes referred to as "Cam-Lock" connectors by their manufacturers, distributors, and/or users.

Roam's MTC 6003 ECKv 200 Amp Generator Interface Boxes accept either #2 to 2/0 or 2/0 to4/0 cables via Cam-Lok plugs on the generator cable side, and from 1/0 to 4/0 cables on the internal wireway side.

Voltages up to 600VAC

Roam offers MTC 6003 ECKv Generator Panels in models that support up to 240 VAC (120v, 208v, 230v, 240v)—MTC 6003 ECK2, up to 480 VAC (277v, 330v, 440v, 480v)—MTC 6003 ECK4-BOY, and up to 600 VAC (575v, 577v, 600v)—MTC 6003 ECK6, which are UL Listed and cUL Listed (Canada) at those voltage levels. Brown-Orange color coding (for labels, Cam-Locks, & Cam-Lock spring caps) is normally used for most 480 VAC applications.

Canadian Color Coding Available

Any Roam panels with power connectors normally color coded (for Cam-Locks, Spring Caps, and Labels) as L1=Black, L2=Red, & L3=Blue, are also available in the typical Canadian color coding format of L1=Red, L2=Black, & L3=Blue. If you need to order a unit with the Canadian color scheme, just add a "-CAN" to the end of the Model Number. If the Generator you are connecting to uses the US color coding (L1=Black, L2=Red, L3=Blue), then you may want the standard US color system (so long as local electrical codes allow).

Spring Caps

These units are also available without Cam-Lock Spring Caps. Roam strongly recommends the Spring Cap version to help protect the Cam-Lock connectors' brass conductors from insects, spider webs, dust, and corrosion. Omit the "K" from the model number to order a version of this panel without Spring Caps.
