Can you splice lightning rod cable?

[hockeyoligist2]

One of our sewer plants needs some roof repair. The contractor noted on the estimate that one of the lightning rod cables is frayed and he recommended replacing it.

I haven't saw it, so I don't know how bad it is. The supervisor over the plant asked me about splicing it. Anyone know if that is OK? I have no experience with Lightning rods.

The NEC is silent on lightning rods splices .

Remember that lightening is very high voltage and amps for a very short period of time. Make your splice with a butt splice instead of wirenuts. Try to maintain a straight line. Avoid curves or keep them very shallow.

As long as the splice is lightning protection rated--why notc ? when installing Lightning protection systems we splice and downsize conductors all the time.

Wirenuts? I doubt wirenuts are large enough.

I check my copy on Wednesday, but off the cuff YES.

I don't think wirenuts are suited for the use.

There are some splice connectors for lightning protection conductors here.
