MC Cable Calculators

The Metal Clad Cable (MC) calculator has functions to estimate the installation time and total weight based on size of the 

• MC Cable Installation Time: Computes the Estimated Install Time for Metal Clad (MC) cable. based on the MC Cable size, length of cable and level of difficulty.
• MC Cable Installation Length: Computes the Length of Metal Clad (MC) cable installed based on an installation time period and level of difficulty. 
• MC Cable Weight: Compute the weight of Metal Clad Cable based on size and length.
• Rolling Offset: Computes the run and travel of a rolling offset configuration.

The Math / Science

Metal clad cable is either a smooth or corrugated factory assembled cable containing insulated circuits (wires).   The relationship between the weight of Metal Clad Cable and the length is shown in the attached table based on industry standards.

The relationship between length of conduit, level of difficulty, size of Metal Clad cable and the time to install comes from industry standard numbers.  The relationship between length of cable, size of cable and the weight comes from industry standard numbers.  The following tables are the basis of the weight, length, and time estimates in this calculator.
