Hi bigcity,
Here is a picture of a hall effect set up.
Here is a picture with a shunt instead.
I don't like the shunt because it IS possible for it to burn out. My understanding is that when that happens since the shunt is in series within the circuit that there will be no power until you jumper around the failed shunt. This is no fun at all at -40. So, if you decide on going with a shunt, make sure it is an accessible location.
I currently use four hall effect sensors in my RV. Two for 12 volt and two for 120 volts. Because of the "donut", with four sensors (and the appropriate switches), I am able to monitor 3 circuits on the DC side and 3 shore power cords on the AC side (the OEM 30 amp and two auxiliary cords).
