Multiple enclosures and repeated conduit work
With the traditional method of installing electrical enclosures, conduit pipes are first brought into a distribution enclosure from either below grade or overhead. From there, installers must measure, cut, and fit individual conduit sections between the distribution enclosure and a separate junction enclosure. After that, additional conduit pieces must be measured, cut, spaced, and installed from the junction enclosure to each individual receptacle or end device.
While this is standard practice, it is extremely labor-intensive. Every conduit section requires measuring, cutting, deburring, fitting, and fastening. In addition, the installation requires multiple enclosures, conduit, couplings, connectors, mounting hardware, and other fittings. Not only do these material costs add up quickly, but the labor required to assemble and install everything is often the largest expense.
