Top Exit of Load Cables for Large Tenant Main (LTM) A loadside wireway section with a minimum width of 12 in. (305 mm) can be used for top exit of load cables. A 12 in. wide section can only accommodate cables for one LTM. A minimum width of 24 in. (610 mm) is required between two LTMs and for NEMA Type 3R applications. Rear load wireway is only available for LTMs and will require increased depth for tenant metering sections. See Rear Load Wireway for more details. |

Top Exit of Load Cables
Tenant metering sections come standard with a front accessible loadside wireway in each section for routing of load cables for top exit. Rear load wireway is not required for top exit applications.
Corner Sections
Loadside Wireway
Rear Load Wireway
Rear load wireway is not available for tenant metering sections < 200 A or in NEMA Type 3R construction. Adding rear wireway to a large tenant main could require increased depth for other sections in the lineup.
