Reply to "ZW-L and track voltage"

Stranded is more flexible without tending to break, including nicking it when stripping. Otherwise they are the same current carrying capacity by definition. In the past there was some talk about skin effect and erroneous info that more skin on stranded would be better, but that is not true unless the skins are insulated individually. Also the frequency of the power is too low for much "skin effect" effect. It may, again if insulated strands, help with the 455 KHz Legacy signal...but that doesn't propagate on the power drop anyway.

So no electrical advantage of solid or stranded.
