What is PVC 20mm conduit?
PVC is a material, Poly vinyl chloride - a type of plastic. 20 mm is a size, probably inner diameter of a cylindrical pipe. Conduit means that it's used to run something like other wires, or a thinner pipe, through.
Can you run two 2 pole single phase circuits in the same conduit?
Yes, this only adds up to four wires. The wire sizing is dependant on the amperage of the two single phase loads. Remember to calculate the conduit fill of the four wires to make sure that you have the correct size conduit for the installation.
Can you run 110 and 220 volt circuits in the same conduit?
Yes, 120 and 240 volts can be run in the same conduit.
Can a three phase circuit be installed in the same conduit or in different conduits?
The conductors of any three phase circuit must be run in the same conduit. If the circuit requires a neutral, it must also run with the conductors in the same conduit. (If they were to be run in more than one conduit or raceway, the circuit would not operate properly.)
What size conduit for 200 amp service?
50 mm or 2 inch will handle the 3/0 wires for a 200 amp service.
