What type of wire do I need to successfully daisy chain the ground connector?
I think it was Knievel that recommended the solid strand doorbell wire from Home Depot (or similar).
a lot of guys around here will recommend sold wire because its easy to make neat but I wouldn't take that advice.
first off, thin gauge solid wire will break easier if its often moved or flexed.
second, crimp connectors are meant for stranded cable. Its very likely to get bad connections if used with solid.
If its any easier, the daisy chain connectors you need are also available already made from most of the vendors.
