What is LFMC?
LiquidTight Flexible Metal Conduit (LFMC) is a type of flexible conduit commonly used to protect cables and wires from water or other environmental damage. It's made up of at least two layers: an inner core of metal that provides electrical conductivity and strength, and an outer jacket made from various materials including PVC, neoprene, nylon, thermoplastic elastomer, polyurethane or rubber. The interior layer can also be coated with corrosion resistant coating for additional protection. LFMC is designed for use in wet locations as well as corrosive environments such as those found near seawater or harsh chemicals. The flexibility allows it to route around obstacles inside walls or raceways and makes it easier to install than rigid metal conduit (RMC). Furthermore, its tight fittings provide an additional layer of protection against moisture intrusion compared to non-liquidtight electrical boxes or fittings.
Advantages of using LFMC
Using LiquidTight Flexible Metal Conduit has several advantages over other types of conduits due to its unique composition and design features. The major advantages include its flexibility which enables easier installation around obstacles such as joists or walls; UL-listed Fire Resistance Ratings (UL-94 V-0); excellent resistance to abrasion; superior corrosion protection; ability to withstand harsh temperatures ranging from -50°C (-76°F) to +90°C (194°F); ability to be used in wet locations; improved protection from animal chewing; and low permeability rating that limits air filtration through the conduit wall thus improving system performance efficiency.
Essential Questions and Answers on LiquidTight Flexible Metal Conduit in "MISCELLANEOUS»UNFILED"
What is LiquidTight Flexible Metal Conduit?
LiquidTight Flexible Metal Conduit (LFMC) is type of electrical conduit used to protect and route electrical wiring in industrial or commercial buildings. It is designed to be highly durable, providing protection from water, dust and debris.
What type of wiring can be used with LFMC?
LFMC can be used with rigid metal conduit, armored cable and non-metallic sheathed cable.
Is LFMC compatible with outdoor applications?
Yes, LFMC is designed to withstand harsh outdoor environments, making it suitable for outdoor applications such as parking lot lighting.
How do I install LiquidTight Flexible Metal Conduit?
Installers must use appropriate tools when cutting and fitting the LFMC tubing. The tubing should be secured at intervals of not more than four feet and connected by approved fittings that provide a complete circuit path for the current being carried.
Are there different sizes of LiquidTight Flexible Metal Conduit?
Yes, LFMN comes in multiple internal diameter sizes ranging from 0.5 inches to 5 inches in diameter depending on the application.
Is LiquidTight Flexible Metal Conduit flame retardant?
Yes, all types of LFMC are certified CSA type ATC for flame retardance. This type of conduit does not support combustion and will not spread a flame along its length.
What voltage rating does LiquidTight Flexible Metal Conduit have?
Depending on the type, most types of LFMC are rated up to 600 volts and 15 amps for usage in dry locations.
Does LiquidTight Flexible Metal Conduit require grounding?
All installations of LFMC require bonding or grounding conductors to ensure continuity of metallic protection both inside and outside the conduit system. Grounding conductors should always be connected prior to connecting any other conductors within the conduit system.
How much weight can LiquidTight Flexible Metal Conduit support?
Most types of LFMC are strong enough that they can support up to 20 lbs per linear foot when properly installed according to manufacturer's instructions. However, this varies between different types and brands so double check with your local code requirements before installing it in any application involving significant load weights.
Final Words:
In conclusion, LiquidTight Flexible Metal Conduit (LFMC) is a type of conduit used by electricians for providing mechanical protection, electrical conductivity and safety when installing cables and wires in any environment featuring wet conditions or corrosive elements. Its construction features multiple protective layers designed for maximum strength, easy installation around obstacles such as joists or walls, superior corrosion protection against saltwater intrusion, UL-listed fire resistance ratings up to V-0 level and improved system performance efficiency due its low permeability rating.
