Can I run this underground from 20amp gfci plug for 50ft to add outdoor outlet? Conduit size?
Asked by Chris January 3, 2020Yes as long as the THHN/THWN conductors are installed in conduit. The voltage drop at a full load of 20 Amps would be below 3% (industry recommendation) for a 50' circuit using 12 AWG CU THHN/THWN. You can use 1/2" Schedule 40 PVC conduit.The above advice is based upon the current edition of the National Electric Code (NEC). Free access to the latest version of the NEC is available online at www.nfpa.org/freeaccess. The NEC and local building codes regulate the types of wire and cable that can be used in specific electrical applications, as well as the manner of installation. Check your local building codes before you start any wiring and cable electrical project and be sure to obtain required permits. When your work is complete, always have it inspected for compliance with local codes to ensure that it has been safely installed.
