Fix Wiring

Lore & Background

Conduit is a tube used to protect and route electrical wiring in buildings or structures. It notes that most conduit is rigid, though flexible options exist for specific purposes. Installation occurs at the site by electricians, following regulations such as the US National Electrical Code (NEC). Conduits provide protection from impact, moisture, and chemical vapors. They allow existing conductors to be withdrawn and new ones installed with little disruption. Metal conduit can shield sensitive circuits from electromagnetic interference, while non-metallic options resist corrosion. Some types are approved for direct encasement in concrete, commonly used in commercial buildings for retail displays or open-office areas. When installed with proper sealing fittings, a conduit will not permit the flow of flammable gases and vapors, providing protection from fire and explosion hazard in areas handling volatile substances.

In Their Own Story

The source does not provide a narrative story involving characters, settings like the Skeld or Airship, or gameplay scenarios. It strictly outlines technical specifications: conduit systems are classified by wall thickness and material. Rigid metal conduit (RMC) is thick-walled threaded tubing made of coated steel, stainless steel, or aluminum. Galvanized rigid conduit (GRC) is galvanized steel used in commercial construction. Intermediate metal conduit (IMC) is heavier than EMT but lighter than RMC. Electrical metallic tubing (EMT), often called thin-wall, is less costly and lighter than GRC. EMT is available in trade sizes 1/2" through 4", and 10′ and 20′ lengths. Aluminum conduit resists corrosion in places like food processing plants but cannot be directly embedded in concrete due to reactions with alkalis. PVC conduit is available in thirteen different size and wall thicknesses, with thin-wall variety only suitable for embedded use in concrete and heavier grades for direct burial and exposed work.

Reader's Guide

It states that conduit installation costs are higher than other wiring methods due to materials and labor, though this is not warranted in all residential applications. Conductors within conduit must have reduced current capacity (derated) if many are installed together because heat dissipation is limited. Wiring regulations prohibit more than 360 degrees of total bends in a run; special outlet fittings are required for longer runs. Metal conduit may serve as a bonding conductor for grounding, but circuit length is limited to prevent high electrical resistance. Joints for PVC conduit use slip-on solvent-welded connections that set up rapidly after assembly and attain full strength in about one day. PVC conduit has a higher coefficient of thermal expansion than other types, so it must be mounted to allow for expansion and contraction of each run. RTRC or fiberglass conduit is light in weight compared to metallic conduits, contributing to lower labor costs, and is available in multiple wall thicknesses.
