System and method for installation of wire including use of flexible metal conduit

A method is provided for installing wire at an installation including delineating a wire run for installing at least one wire within the installation and identifying at least one first portion of the wire run requiring a metal protection for the wire and at least one second portion of the wire run not-requiring a metal protection for the wire, where the first portion includes at least one non-linear segment. For the first portion, at least one continuously welded corrugated flexible metal tube is installed for the first portion, where at the non-linear segment the corrugated flexible metal tubing is manually bent to fit a path of the wire run. A wire is installed through the first and second portions of the wire run, where during the portions of the wire run in the at least one first portion, the wire is passed through the corrugated flexible metal tubing.
