Looking for a design to activate a solenoid when a set current is exceeded in an AC circuit.

I have a home made diesel generator. What I am looking for is a circuit that when current exceeds 5 amps it activates the high idle solenoid. I see many that sense when any load turns on, but I would prefer slightly higher activation threshold.
Thank you for any help folks.

You can get the ACS712 modules on ebay for about $2.00
They come in different current limits.
I would suggest looking for one with the substantial terminals as some come with very small under rated type.
