What type of fitting is recommended where PVC conduit is connected to a box or enclosure?
Use a non-metallic PVC connector with PVC conduit. Locknuts are used to fasten conduit fittings to a box or enclosure. Insulating bushings are used to protect the wires from the sharp interior edge of the fitting. This is especially important when pulling wire into an electrical box or enclosure.
Is it OK to run Romex in PVC conduit?
No, you can not run your Romex wiring in conduits. What you're looking at in the code book is referring to THHN and other wiring, that while insulated with a single coat is not insulated with a second covering and bound to 2 or 3 other wires. Power produces heat and heat is the main problem here.

Steps to Connecting the Conduit to the Electrical Box
With all the items you’ve gathered from the hardware shop, gear yourself up and get to work with this PVC electrical conduit installation guide.
Conclusion
So that’s it! Remember that the most crucial part of learning how to connect PVC conduit to an electrical box is deburring the rough edges after cutting the pipe. Many people forget to do this part, and once they fit the tube inside the fittings, there are still sharp plastic remains that can eventually damage circuits.
How to measure electrical conduit?
Measure the amount of conduit that you would need: Make appropriate marks in pencil wherever you think the bends should be , and measure the total length of the conduit that would be needed to finish the entire electrical conduit fitting s. Now cut the length that you just measured with a tool called hacksaw.

What is conduit connector?
Conduit always terminates at some type of electrical box or at fixed equipment that also serves as a box. Special connectors are used to secure conduit to boxes and to join lengths of conduit together to form long straight runs or bends. The boxes, connectors, and conduit form a wire enclosure system called a raceway.
What type of wire is used in conduit?
The types of wire most commonly installed inside of conduit are THHN and THWN. THHN/THWN wires are individual, insulated, and color-coded wires. They are similar to the wires you see when you strip the outer sheathing off of NM cable.
What is conduit used for?
Special connectors are used to secure conduits to boxes and to join lengths of conduits together to form long straight runs or bends. The boxes, connectors, and conduits form a wire enclosure system called a raceway. A raceway is an enclosed conduit that forms a physical pathway for the electrical wiring to follow. In this way, the metal raceway acts in place of the grounding wire that is found in non-metallic cable. (This is also the main reason why only metal boxes may be used with metal conduit.)
What is EMT conduit?
EMT: Electrical metallic conduit is rigid, thin-walled metal conduit typically made of galvanized steel.

What Are Conduit Fittings?
Conduit fittings allow you to make connections in an electrical system. They can connect two runs of conduit or secure conduit to an electrical device. These types of fittings are commonly called conduit fittings and electrical fittings to separate them from types of fittings used for plumbing.
Adapters
Adapters serve as connectors in an electrical system. Adapters are designed to:
Bushings
Metal conduits may have sharp edges. If left exposed, the edges may snag or damage wiring. Bushings fit into the ends of metal conduit to cover up the sharp edges and protect wires. Depending on the type of bush fittings you choose, they may snap, slip or screw on.
Couplings
Couplings join materials of the same type together to form a longer straight line of conduit. Three main types of couple fittings are available:
Elbows
Similar to couplings, elbow fittings join like with like. The difference is that elbow couplings introduce a gentle curve to the length of conduit. Pulling wire through an elbow coupling is often easier than trying to thread wires through a sharp 90-degree right angle.
Straps
A conduit strap secures a length of conduit to a wall or a joist. Using one helps reduce sagging that can cause conduit to break. Many straps have an arch that fits around the conduit. One or two holes may be pre-drilled into the strap to simplify mounting.
Connectors
Connector fittings live up to their name by connecting components of an electrical system. You may use them to:
