Underground Wire Cut
I'm a homeowner, not an electrician. I had a lampost installed outside which goes from a GFI receptacle out to the lamp. I cut into it while digging by the post. I taped it as a temporary fix and be damned if it didn't work. Well, for a while. The GFI breaker now will not reset. I suppose it is just shorting out due to moisture. I know I need to splice this properly and that there is an underground kit. First, is this something I should have a pro do? Is it something a reasonably handy homeowner can handle? Which underground cable splice kit should I use?
Any tips will be greatly appreciated.
