A cable pull calculator may be provided. First, wire number data, a wire type, and size data may be received. Next, a minimum conduit size for the conduit maybe calculated based upon the received wire number data indicating the number of wires to be placed in the conduit and the received size data corresponding to each of the wires to be placed in the conduit. Then, the calculated minimum conduit size may be displayed. Next, a first desired conduit size, a conduit type, and pull information indicating a course of the conduit may be received. Then, for each of the plurality of segments, a tension value and a sidewall pressure value may be calculated based at least on the conduit type, the first desired conduit size, the received wire type, and the received size data. The calculated tension value and the calculated sidewall pressure value may then be displayed. |

1. A method for providing cable pull calculations, the method comprising:
receiving wire number data indicating a number of wires to be placed in a conduit wherein receiving the wire number data indicating the number of wires to be placed in the conduit comprises receiving the wire number data indicating the number of wires to be placed in the conduit wherein the wires comprise at least two wires wherein the at least two wires comprise a phase wire and a neutral wire; receiving a wire type corresponding to each of the wires to be placed in the conduit; receiving size data corresponding to each of the wires to be placed in the conduit; calculating, by a computer, an ampacity of the wires to be placed in the conduit; displaying the ampacity; calculating a minimum conduit size for the conduit based upon the received wire number data indicating the number of wires to be placed in the conduit and the received size data corresponding to each of the wires to be placed in the conduit; displaying the calculated minimum conduit size; receiving a first desired conduit size; receiving a conduit type; receiving pull information indicating a course of the conduit, the course comprising a plurality of segments, each of the plurality of segments comprising at least one of the following: a straight section and a bend section; calculating, for each of the plurality of segments, a tension value and a sidewall pressure value based at least on the conduit type, the first desired conduit size, the received wire type, the received size data, and the received pull information; and displaying, for each of the plurality of segments, the calculated tension value and the calculated sidewall pressure value, wherein for each of the plurality of segments,
the displayed calculated tension value indicates when a maximum tension for the wires has been exceeded, andthe displayed calculated sidewall pressure value indicates when a maximum sidewall pressure for the wires has been exceeded. |
