Thomas & Betts LTZUS03B-L – Frequently Asked Questions
1) What size conduit is the Thomas & Betts LTZUS03B-L and how much comes on a reel?
It's 3/4 inch trade size liquid tight flexible metallic conduit, supplied as a single continuous 1,000 ft (300 m) reel. That's a bulk put-up meant for a job trailer or a shop stocking shelf, not a short whip length, so plan for one reel to cover a lot of motor connections, rooftop unit drops, or machine hookups.
2) Is the LTZUS03B-L metal conduit or plastic?
Metal core. The LTZUS03B-L is built on a galvanized steel core with a black outer jacket, which is what separates liquid tight flexible metallic conduit (LFMC) from the nonmetallic LFNC types. If your spec or drawing calls for LFMC, this is the metallic family. If it calls for LFNC, this is not the right material.
3) Can I use this black liquid tight conduit outdoors or in a wet area?
Liquid tight flexible metallic conduit is the type used where a flexible raceway has to keep liquids out, such as rooftop HVAC equipment, pump and motor terminations, washdown areas, and exterior equipment drops. The black jacket over the galvanized steel core is the standard finish for that use. Termination has to be made with proper liquidtight fittings for the assembly to stay sealed.
4) Why use flexible liquidtight instead of rigid conduit or EMT for a motor connection?
Flexible metallic liquidtight is the right choice on the last few feet into rotating or vibrating equipment, where rigid pipe or EMT would transmit vibration and make alignment and future removal difficult. Run EMT or rigid for the fixed portion of the raceway, then transition to a short length of this 3/4 inch LFMC for the final connection to the motor, compressor, or machine.
5) What is the exact part number to order this Thomas & Betts 3/4 inch liquidtight reel?
Order it by manufacturer part number LTZUS03B-L, Thomas & Betts. One part number covers the whole item: 3/4 inch, black, 1,000 ft reel. There are no finish or length choices to specify with it.
6) Does 3/4 inch liquidtight metallic conduit give me an equipment ground, or do I still pull a ground wire?
Pull a separate equipment grounding conductor. The conduit is built on a galvanized steel core, but on flexible metallic liquidtight the metal core is generally not relied on as the sole equipment ground except within the limited lengths and sizes the code permits with listed fittings. Standard practice on motor and equipment whips is to run a green ground inside the conduit and land it at both ends.
