I purchased an un shunted 30 amp ammeter so i could learn how rto wire it in with a shunt
I WILL ENCLOSE A PHOTO BELOW.
The shunt is rated at 80 amps and has a 75mv something. I see the meter has a 75 mv movement.
The shunt has 2 terminals at each end. One large and one small.
Each set of terminals on either end of the shunt is on a metal block and electrically shorted to one another.
I realize that the shunt must be in series with one leg of the supply voltage (( In this case 220 volts.)) The thing that has me confused is the 2 diferent size terminals.
Normally i would just say that the larger terminals are for the hot wire and the smaller terminals for the meter. BUT BUT Resistances in series tells me that the meter will be the path of least resistance and blow out when current flows.
HELP PLEASE!!!!!!!!!
