What type of wire?

Forum Title: What type of wire?

I did a small panel change on Friday. Existing were fuses with a 60amp main. They didn't want to do service upgrade, only get rid of the fuses. They did want to however install a 125amp panel for future possible upgrades. The se is "anaconda" #2 copper. What wire type is this? What do they coat the strands with to give them the gray coating on the outside?

I don't have any specific info on Anaconda SE cable, but tin, silver or nickel are commonly used to coat annealed copper wire like that.

the coating did have 75deg on the coating. Is it considerid copper and can I use that column of 310.16 in the copper ampacity chart for it? Just trying to make sure I put the proper size breaker in. The panel had a 60amp breaker, but if I could put in a 100amp main in that would save them a service upgrade. It was acutally #3, not #2.

I will take this a grain of salt due I do not have the NEC chart with me at the moment but IIRC the smallest unground conductor you can use for 100 amp service is #4 or 25mm? one of the two but becarefull some inspectors may reject that and have to use #2 or 35mm² conductors size so that kinda of fineline to walk on this one.Merci.Marc
