I did talk to an electrition today who would look it over for free. Since the line runs underground, it would be under $100 to fix, however the guy said he would do the same thing i would, dig the wire up, splice it and bury it.
Well, you said you spliced it with electrical tape. I assume this "qualified" guy will be doing a little more than that. I'll also be interested to hear his opinion of an unprotected cable being 6" from the surface.
I assume you didn't take him through the rest of your system, with your single cable being on a 60A fuse, etc?
