I recently took a journeyman exam in NM. There were a few questions I couldn't find answers to if anybody could help that be great.
1- Wire splices under vaults need to be supported at how many inches on either side of splice. 2 4 5 6 I have never heard of splices under vaults.
2- Scratches and minor defects in wire cause what? Resistance, voltage drop and I don't remember the other two options.
3- What is the primary function of the metal coating on underground communication cable?
