Arduino clamp ammeter
An AC clamp meter won't read DC. 

The ACS758KCB-150U is a Hall effect current sensor rated for 150A. It has a sensitivity of 26.7mV/A, which equates to 3.5V at 130A. Most A/D converters should be able to measure this voltage without amplification.

The advantages of a Hall effect sensor over a shunt resistor are galvanic isolation and very low insertion loss. A 50mV current shunt dissipates 5 Watts at 100A. The ACS758KCB-150U has a resistance of 0.0001 Ohms, so it only drops 10mV and dissipates 1W at 100A.    

However it does have one disadvantage - magnetic hysteresis. After passing a current of 150A, lower current readings may be out by 0.2A. If you are just checking for overloads and don't need high accuracy at low current then this shouldn't be a problem.
