Electrical Conduit Specifications

Help with Electrical Conduit specifications:

Material

	Material
	Your choices are...
	Aluminum		Aluminum is a common industrial conduit with good electrical and thermal conductivity, high reflectivity, and resistance to oxidation.
	Fiberglass		There are three types of fiberglass conduit: standard, XW type, and phenolic. Standard is for basic industrial applications; XW type is used in Class 1 Division 2 applications, and phenolic are used in high temperature electrical applications.
	PVC (Polyvinyl Chloride)		Polyvinyl chloride (PVC) is a widely used material that has good flexibility, a smooth surface, and nontoxic qualities. Some grades are used in food and chemical processes due to the inert nature of PVC. Chlorinated polyvinyl chloride (CPVC) is a grade of PVC engineered to withstand higher temperatures than standard PVC.
	PVC Coated Aluminum		Aluminum is coated with a polyvinyl chloride (PVC).
	PVC Coated Steel		Any steel grade with a polyvinyl chloride (PVC) coating.
	Nylon		Nylon grades, such as 6/6, can offer flexibility and good water resistance.
	Polyester		Polyester is a family of grades of thermoplastics with good toughness and sometimes high flexibility.
	Polyethylene / HDPE		Polyethylene or high-density polyethylene (HDPE) is a light, tough plastic with excellent corrosion resistance and good water barrier qualities.
	Steel		Basic multipurpose steel conduit.
	Galvanized Steel		Galvanized steel has a protective coating of zinc for resistance against corrosion. Galvanized coatings are rated by their weight and carry designations such G30, G60, and G90. Heavier coatings generally provide higher corrosion resistance.
	Stainless Steel		Stainless steel is chemical and corrosion resistant and can have relatively high pressure ratings; this selection includes all grades of stainless steel.
	Urethane Coated		Polyurethane or urethane refers a diverse class of materials exhibiting good elongation, recovery, and toughness properties. They are flexible and have good abrasion resistance, and urethane coated metals are used in conduit for many applications. (NOTE: The urethanes of the plastics industry are so named because the repeating units of their structures resemble the chemical urethane.)
	Other		Other unlisted, proprietary or specialized material.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
	Conduit Size		Size of conduit.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Temperature Rating		Temperature range the product is rated at.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Units of Measure
	Your choices are...
	English Size		Measurement uses the customary U.S. system of unit.
	Metric Size		Measurements are made to metric size standards.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
	Features
	Your choices are...
	Rigid Conduit		Rigid conduits maintain straightness and stiffness. They are not meant to be bent.
	Flexible Conduit		Flexible conduits are constructed of material that can be field bent or aligned for ease of installation.
	Hazardous Location Rated		Conduit is rated to withstand severe conditions of heat, flame, explosion, etc.
	Fire Alarm Conduit		Fire alarm conduit frequently has special ratings and color coding and labeling to signify its importance in building safety.
	Prewired Conduit		Conduit with appropriate wire or cable already installed in the conduit.
	Underground Rated		The conduit is designed and constructed for underground application.
	Liquid Tight		Materials, construction, and seals are designed to prevent any ingress of water or other liquids.
	Magnetic Shielding		Magnetic shielding attenuates magnetic fields to protect sensitive equipment, such as computers.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Type

	Your choices are...
	IMC		Intermediate metal conduit (IMC) has rigid circular raceways with thinner walls than rigid metal conduits (RMC), but the same outside diameter.
	RMC		Rigid metal conduit (RMC) is thicker-walled and therefore heavier than intermediate metal conduits (IMC), with the same O.D.
	GRC		Galvanized rigid conduit (GRC) is metal conduit that has been coated with zinc, and often other agents, to increase resistance to abrasion and corrosion.
	FMC		Flexible metal conduit (FMC) has a helically-wound circular wireway, often used at the end of a rigid run to accommodate for machinery positioning or orientation.
	LFMC		Liquid tight flexible metal conduit (LFMC) is constructed as flexible metal conduit (FMC) with a liquid tight plastic covering over the flexible metal core.
	RNC		Rigid nonmetallic conduit (RNC) is made from different types of plastics and is typically for areas that are wet or corrosive.
	NUCC		Nonmetallic underground conduit with connectors (NUCC) is somewhat flexible, corrosion-resistant, and contains the electrical conductor’s factory installed inside the conduit. They may be supplied in reels for field installation, and constructed to be tough enough to withstand the stresses of field placement.
	LFNC		Liquid tight flexible nonmetallic conduit (LFNC) features a liquid-tight jacket over an inner flexible, nonmetallic core. They may be reinforced or corrugated to improve strength.
	EMT		Electrical metallic tubing (EMT) has a circular wireway with much more workable properties than intermediate metal conduits (IMC), or rigid metal conduit (RMC). They may be cut, formed, and bent more easily.
	ENT		Electrical nonmetallic tubing (ENT) is a circular, corrugated wireway typically made from PVC.
	Other		Unlisted, proprietary, or specialized class of conduit.
