Power facilities available on caravan sites can vary between 6-16amps and if exceeded trips the supply. Thinking of fitting a 0-20amp AC ammeter in series with 240volt supply in my caravan. Found a digital meter (requires a 12dc supply) complete with 20amp shunt.
Would like to know if this sounds okay and should the dc supply to the meter be fused ?What kind of volts drop across the shunt should I expect ?
Many thanks in anticipation
