Electrical wiring

[Rawze]

FOr the bigger wires, like the 4/0, I always solder the connections, not crimp them.. much higher reliability, and less chance of bad connection later on. - As far as sealing the ends (exposed copper after making the connections), I use cloth tape, painted with a thick coat of flex-seal (in the can, not the garbage spray they sell).--- lasts for years without worry.

cloth tape, you can get at walmart or on amazon. here is what i use... https://amzn.to/2sZCbB8
