sorry, your second point is not quiet clear. are you referring to my question about mixing 0.5 mm and 0.7 mm gauges ?2) You will have long runs of uninsulated wire. This poses the risk of things touching each other when they really shouldn’t be touching each other.
if so, i will do this because the 0.5 mm wire i have is solid core (LAN wire), and the 0.7 mm wire i have is stranded so that would be more flexible to work on the ground daisy chain.
my question was is it safe to use both gauges ?
