What is a slip meter riser?
Carlon’s line of slip meter risers is engineered to provide a smooth transition from rigid or corrugated conduit underground service to the electric meter. Fitted with a terminal adapter to provide an easy hook-up at the service entrance location, slip meter risers are a low-cost method of complying with NEC.
What is a conduit expansion joint?
All conduit pipe and fittings expand and contract with changes in temperature. In installations where the expected temperature variation exceeds 25°F expansion joints must be used. An expansion joint consists of two tubes, one telescoping inside another.
Can PVC be used for electrical conduit?
Polyvinyl chloride (PVC) is a combination of plastic and vinyl that is used to make PVC pipes. These popular types of pipes are commonly used in plumbing as an alternative to more expensive copper piping. PVC is also used to produce electrical conduit.
What is riser in electrical?
Riser, a length of vertically oriented piping used to deliver fluid, gas, or electrical signals or power upward.
Where should PVC expansion joint be installed?
The expansion fitting must be installed close to the top of the run with the barrel pointing down, so that rain water does not enter into the opening. The lower end of the conduit run should be secured at the bottom. This will result in an upward movement due to the length change caused by temperature variations.
Can PVC expansion fittings be used underground?
Do you guys ever worry about PVC expansion fittings in underground installations? No, never. They aren’t listed for direct burial anyway.
What is a slip coupling PVC?
Slip Coupling for Schedule 40 PVC Pipe (Slip x Slip). The easiest way to connect two pieces of pipe of the same size is with a slip coupling. Slip couplings are used when the pipe doesn’t need to be taken apart and you are simply joining two smooth pipe ends together.
Does PVC conduit expand?
Like all materials, PVC expands with increasing temperatures and contracts with decreasing temperatures. Because the length-to-diameter ratios of PVC pipe and conduit products are generally very large, length change from temperature variation is the most noticeable.
