Using PVC Conduit for Electrical Wiring

For a safe and long-lasting solution to electrical wiring, you can install PVC (non-metallic) conduit. You may find that it is less expensive to run conduit for heavy duty circuits to the stove and dryer as compared to buying a full 250 ft roll of Romex or BX cable, but CHECK THE LOCAL BUILDING CODES! The conduit is used in conjunction with single-stranded wire. You can run conduit yourself (assuming you are the homeowner, have a licensed electrician willing to work with you and local codes allow for this). Compared to metallic conduit, PVC is less than 1/3 the weight and easier to work with.

Step 1:

First you will need to plan your route from the breaker panel to the receptacle box. It is important to understand that pulling wiring depends on the number of bends, so look for options which will minimize bends. Typical conduit sizes for residential application are: 3/4", 1" and 1-1/2" diameter, but can be up to 6" in diameter. Remember, the larger the wire size (for example,10 or 6 gage strands), the larger the conduit you will need. Let the electrician determine which size conduit you will need.
