Power Take-off Sections➁➂<br />

Power take-off sections are used in the following situations:<br />

1. To take large amounts of power off a run (beyond the current<br />

carrying capabilities of plug-in stabs).<br />

2. Where space restrictions dictate that the wide dimensions<br />

of the busway be flat against a wall or ceiling or other obstructions,<br />

bolt-on units are used instead of plug-in units.<br />

3. Where panelboards are mounted on busway.<br />

The plug-in power take-off is a design that permits the take-off<br />

of power (1600A max.) at a standard plug-in opening. The molded<br />

insulator in the opening is removed completely. The power<br />

take-off conductor is inserted into the opening until contact is<br />

made with the bus bars in the bus duct. A single bolt design in<br />

the power take-off is then torqued to 60 ft.-lb., permitting 1600A<br />

maximum capacity.<br />

The bolt-on circuit breaker, fusible switch or tap box is then<br />

bolted to the power take-off by solid buswork. The plug-in power<br />

take-off cannot, in itself, be used as a cable tap box. An overcurrent<br />

protective device must be priced with the power take-off.<br />

This device for load applications as shown.<br />

➀ Right leg must be 24 inches.<br />

➁ When laying out the bus run, “T” and “F” must be shown.<br />

➂ Built-in power take-off device, 1250-amp max.<br />
