How do you calculate the pull tension for a cable?

P = Tb / r (Formula 6) Where:P. = actual sidewall pressure on cable, lbs./ft. Tb = pulling tension at and of bend, lbs. The maximum allowable pulling tension at bend (Tbm) is the limit that the calculated pulling tension (Tb) should be compared.

How far can you run wire before voltage drop?

As an example, for a 120-volt circuit, you can run up to 50 feet of 14 AWG cable without exceeding 3 percent voltage drop….For 120-volt circuits:

14 AWG	50 feet
10 AWG	64 feet
8 AWG	76 feet
6 AWG	94 feet

How do you calculate pull?

Divide the force in Newtons by the area in mm2 and the pressure is calculated (in Pascals or N/ mm2). The pull force is given as a pull of the magnet perpendicular to the ferromagnetic surface. But the magnets can slide along the surface with a shear force.

What size wire do I need for a 200 foot run?

Generally speaking, you will need 1 AWG copper or 2/0 aluminum conductors for this to work. This should be large enough wiring to safely carry those 100 amperes. It will also maintain the power quality over larger distances.

What do you mean by Conduit Fill on Southwire?

From vision to completion, we’re here to help you along the way. Learn more about Southwire’s history, impact and reach. Conduit Fill is the percent of area inside the conduit taken up by the cable (s). Provides quick and easy results for the conduit fill percent, per NEC® guidelines.

What can a cable calculator do for You?

Helps to estimate and manage cable installation projects. Provides the ability to alter data that indicates tension or sidewall pressure. Optimizes jobsite installations with faster quotes and direct wire requests.

What is the Conduit Fill percent of MC Cable?

Conduit Fill is the percent of area inside the conduit taken up by the cable (s). Provides quick and easy results for the conduit fill percent, per NEC® guidelines. Quickly and easily illustrates the potential labor cost savings when using MC AP ® cable in place of traditional MC cable.
