Question:
Hello, what is the amperage rating for underground wire installed in a PVC conduit? Thanks Mike Wood.
A
Answer:
Hi Mike, thanks for your question. The conductor material, size, and insulation type/rating are needed to determine conductor ampacity.
Section 310.14, and Table 310.16 provide guidance on determining the ampacity of conductors. Additionally, see Section 310.15 and associated Tables for information on the conditions that may require the conductor ampacity to be adjusted.
