Re: [volt-nuts] Best way to measure micro Ohms

I guess I would have to ask, "How do you know everything was done 'right'?" The evidence you have stated makes a pretty good case that it wasn't. The neutral entering a sub panel at most has the same current going through it as one of the line input leads, though in a 240V sub panel, load

Re: [volt-nuts] Best way to measure micro Ohms

I once repaired a Valhalla 2555A Current Calibrator (good for up to 100A output). It uses aluminum bus bars inside to route the current. The junctions between the bars had become higher than normal impedance and it could no

Re: [volt-nuts] Best way to measure micro Ohms

Hi, just my $0.02 worth. I have some instrumentation amplifiers here also looked into low resistance connections for my other projects. If I recall correctly you need to look at the electrochemical series. For interconnects on Al you want a metal similar on the ES. The oxide is a problem but if
