Customer ground and phase power connections are made in the bottom left half of the unit. All connections are
made from the front.

the input bus or other connections inside the unit.

Cable entry/exit can be from the top or bottom of the unit.
The preferred cable entry/exit is from the bottom, which locates cables closer to the source and output power
busses and ground bus. For top cable entry/exit, cables can be run down along the inside rear of the unit.
Identical removable conduit panels are on the left side of the unit, top and bottom. There are no knock-outs in
the panels; installers must make their own conduit cut-outs. TFA STS 800-1200A units have (12) possible 4"
conduits per conduit panel assuming 6" dia. area per conduit as shown in
Figure 25 .

Customers can specify a preference for bottom or top cable landing. If top cable landing is preferred, the TFA
STS unit can be manufactured with a Top Cable Landing Compartment. This configuration choice reverses the
positions of the MCSWs and the cable landing compartment from the normal TFA STS layout. Unit dimensions,
power connections, and operation are otherwise the same as for standard units.
