With the price of direct burial cable vs the price of 60ft of conduit, there's no reason not to have it properly protected. As for the rest, it's not a whole lot more work than getting it properly put up above ground, and reduces the potential for future issues.jimlongley wrote:But there won't be any conduit unless you provide it, and fish it, and have your electrician wire it (it won'r be legal for you to wire it unless you are a licensed electrician) and hook it up.
And none of which address the fact that there are already things running under my yard that will cost me a lot if I break them. Therefore, I avoid breaking them. The simple fact is, I don't have drunken backhoe contests in my yard, and any contractor I hire is insured against such things.And of course, it wouldn't have to be your dog that dug it up, maybe you decided to plant some roses or fence posts along the property line of the house you just bought with buried facilities, and you hit them yourself, I can posit literally thousands of possibilities, most of which would not involve your ninja trainer.
Why would I (or any electrician worth using) look for the fault? It's 60 feet: unhook both ends and pull it out, using it to fish a new line in the process. We're not talking about a five mile run that needs heavy machinery. I don't use a TDR on the cable for my mobile antenna when it fails for the simple reason that anything requiring more than $30 worth of equipment is more expensive and time consuming than pulling a new cable.Don't forget, I spent an entire career dealing with buried and underground facilities. Everything on your side of the meter is your responsibility, and you can denigrate the 60 feet of wire as being mere bagatelle, but when it comes to dealing with a buried fault, it is very complicated to find and fix.
But have you ever seen an overhead residential water supply or sewer? I bet the same specialized techniques that allow water pipes to be buried will work with conduit when properly applied.I have seen buried power service drops, put in by the power company, not by an electrical contractor hired by the homeowner, that ended up almost on the surface after final grading and erosion took place.
