Wire Type

I just started polling my display out of storage and noticed much of the 16/3 & 16/2 wiring is showing signs of deterioration. Looks like I'll be changing it. Recommendation on wire type and a vendor would be appreciated. Thx!

Is something eating the plastic coating off the wire, Maybe you need some shielded wire. Best to buy local to save on freight.

out of stock atm so I can't see Ag rating.

No its the Sun and cold causing discoloring and some cracking. Thanks for the recommendation. I ended up buying from my local Lowes vs. looking for a good deal on ebay.
