Simply so, what is the difference between ser and Seu?
SER and SEU cable types are constructed with sunlight resistant Type XHHW-2 conductors or Type THHN/THWN conductors. The main difference between SER cable and SEU cable is that SER cable has reinforcement tape while SEU has an overall concentrically applied neutral and reinforcement tape.
Likewise, people ask, what is URD cable?
URD Cable / Wire. The underground residential distribution (URD) wire has a conductor made up of strands of compressed aluminum alloy 1350 series. It is insulated using cross-lined polyethylene (XLPE) that is black in color. Its phase conductors and assembled together with neutral conductors forming a twisted cord.
When it comes to the lines connecting master and secondary panels, where the line will carry as much as a full 100 amps, use a 2-gauge non-metallic sheathed electrical cable. The cable must contain one or two hot wires depending on your needs, one neutral wire, and one ground wire. Each wire should be 2-gauge in size.
