Manual Transfer Switch Cam-Lock Panel
Three-Phase 200A
MTC 7003 ES2Kv
Roam's MTC 7003 ES2Kv series ("v" = Voltage Code) of 200 Amp Manual Transfer Switch panels provide a secure and easy-to-connect Cam-Lock connection between a generator and building main power, letting you switch a building main circuits (by means of physically turning a switch) between utility power and generator power. Roam's Manual Transfer Switch (MTS) panels combine a Generator Connection Box and a Transfer Switch, providing a single-panel solution for exterior connection and switching of emergency power. Roam's MTS panels are UL 1008 listed and use E1016 (J-Series/16 Series) Male Cam-Lock connectors.
Roam's line of MTS panels includes Service Entry Rated panels, Switched Neutral panels, and panels with no Neutral connection. These panels are all built with a dedicated wire chase (wireway) in the back to allow safe cable entry (via conduit) from the bottom. Roam's MTS panels all use Open (Open Transition) transfer switches, with On-Off-On corresponding to Utility-Off-Generator positions.
The standard in safety and outdoor reliability, Roam's line of NEMA 3R rated Manual Transfer Switch boxes makes connecting—and switching power from—a portable generator to your site fast, easy, and most importantly safer. 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.

Connections
Roam's MTC 7003 ES2Kv series 200 Amp Manual Transfer Switch boxes accept either #2 to 2/0 or 2/0 to 4/0 cables via Cam-Lock plugs on the generator cable side, and from 6 AWG to 350 MCM cables on the internal wireway side. All cables used should be specified by a qualified electrical designer or electrician to support the maximum possible current draw through a specific connection.
Voltages up to 600VAC
Roam offers MTC 7003 ES2Kv series 200 Amp Manual Transfer Switches in models that support up to 240 VAC (120v, 208v, 230v, 240v)—MTC 7003 ES2K2, up to 480 VAC (277v, 330v, 440v, 480v)—MTC 7003 ES2K4-BOY, and up to 600 VAC (575v, 577v, 600v)—MTC 7003 ES2K6, which are UL Listed at those voltage levels. Brown-Orange color coding (for labels, Cam-Locks, & Cam-Lock spring caps) is normally used for most 480 VAC applications.
Service Entry Rated Option
Many of Roam's MTC 7003 ES2Kv series Manual Transfer Switch panels are Service Entry rated, meaning that these panels are suitable for use as service equipment/service disconnects. A service disconnect is simply the first disconnect between the external power source (utility or generator) and building main circuits. All of our Service Entry rated MTS panels have a "-SE" extension in their part number. Service Entry rated panels are available with a standard UL listing (USA), but not with a cUL (Canadian) listing.

Switched Neutral Option
Normally, MTS panels are built with the Neutral connection not running through the Transfer Switch (frequently referred to as a "solid" Neutral). However, Roam does offer a Switch Neutral option, where the Neutral connection is switched through Transfer Switch (i.e., an additional pole runs through the Transfer Switch). Switch Neutral panels are typically used when the generator is grounded as a separately derived system at the site. It is important to be aware that Switched Neutral panels can not also be Service Entry rated under UL 1008. We advise that before selecting a Switch Neutral option, you should consult a qualified electrical designer who is familiar with your site and local electrical codes. All of Roam's Switched Neutral rated MTS panels have a "-SN" extension in their part number.

No Neutral Options Available
Roam's 400A Manual Transfer Switch panels (boxes) can also be ordered with no neutral connection for sites and generator configurations designed for just Ground, L1, L2, and L3 cables. The "No Neutral" versions of these panels are also UL Listed. To order a panel without a neutral connector just add a "-NN" to the end of the Model Number. The "No Neutral" panels use only four Cam-Lock connectors.

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 you are connecting to a generator that 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). Note that Service Entry rated panels are not cUL listed.
Spring Caps
Roam's MTC 7001 ES2Kv panels 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.
Model Numbers & Options
| Base Model Number | Up to 240VAC | Up to 480VAC | Up to 600VAC | No Spring Caps |

The "v" in the part number represents a code of either 2 (for up to 240 VAC panels), 4 (for up to 480 VAC panels), or 6 (for up to 600 VAC panels).
For the No Neutral option, add "-NN" to the base model number. For the Service Entry rated option, add "-SE" to the base model number. For the Switched Neutral option, add "-SN" to the base model number. Switched Neutral panels can not also be Service Entry rated under UL 1008. For the Alternate Wire option, add "-ALT" to the base model number.
