Has anyone thought about or installed an A/C or D/C ammeter? I was looking at them online and it seems that A/C amps might be useful to know. It could show if one is approaching the circuit breaker limit, in my case 30A. This is a link to one that is 2 3/4" size. A 2" version is also available. http://www.marinedeal.com/product_p/s9630.htm
One advantage of the A/C ammeter is a more simple hookup. Just a induction coil that slips around the wire being measured. It can be calibrated by a set screw with a known load. For example a 1500 watt heater draws about 12 amps on high. (Amps=Watts/Volts)
On the D/C side I found a link to instructions for a Blue Sea D/C ammeter. I cannot make heads or tails of it as relates to a teardrop. http://bluesea.com/files/resources/inst ... s/9878.pdf I have a converter that can power the teardrop DC and charge the battery if the battery switch is on. The battery can power teardrop D/C if the battery switch is on and the converter is not powered. I would like to read the D/C amps being used and/or battery rate of charge/discharge. Any help in this area would be most appreciated. I am totally confused on how to connect a D/C ammeter to provide useful information.
Maybe it would be nice to have both A/C and D/C ammeters if one is really into gages. I already have a D/C voltmeter and switch that can measure either battery or converter output voltage. In a previous life my work involved reference to gages and this may be part of the reason I am interested in adding one or two.
