How do I find the right size wire nut for joining electrical wire together?
Does anyone have a link/website that shows which size/color wire nut to use for connecting different guage size wires?
What should I be looking out for when screwing on the nut to the wires. Is there anything that I will notice when I have found the correct size?
Is the color of the nut standard from one manufacture to another?
thanks
yellows - 2 number 12s 3 number 14s
tans - up to 3 number 12 wires, 4 number 14s
reds - up to 5 number 12s, 3 number 10s
grey - 4 number 10s, 3 number 10s 2 number 8s
blues ( big ones ) - , 3 number 8s 2 number 6
the colors go from smallest to biggest in size this line up is from Ideal , but most manufactuer's follow color/ sizing convection, they do make a smaller blue and smaller grey, but these are for low voltage work of for florescent lighting secondary connections where the voltage is high, the wires are small and the amperes low
do not use Scotchloks by 3M
they are soft bodied and do not grab well and may lead to arcing even though they are still UL listed
no good electrician that I know of uses them
