What gauge wire for N-G bond?

I have a jumper connecting load neutral to chassis in my inverter.
Maybe called a N-G bond? Not sure of the terminology.
Does this wire need to be a particular gauge to be effective?
Currently it's just a very thin 18AWG.
 
Gonna be reading about another fire here one day.
Inverter manual and local code will tell you everything you need to know.
 
Usually whatever wire size it calls for your hot wires is the same size you need for your ground and neutral wires. I.E. if it wants 12awg wire for the AC, use 12awg for the ground.
 
Well, there should be zero current on the n/g bond...
Unless there is a fault.
#4 solid is the max residential grounding conductor...
 
Mom said it's my turn to have the electron.

Anyway, is the 18 awg just a signaling wire for a bonding relay? If 18 awg came on the inverter I doubt it's supposed to be the bonding conductor itself. Who knows what they'll pass off though.

Depends if you use islanding mode.
Manual stipulated the wire size to use with your inverter

Furthermore, that bond, if you are using a permanent bond, should be made in the breaker box and not your inverter.
Here that would be a very serious violation of code
 
Back in the day when I done service upgrades, The NEC required NO#6 solid copper for any 200amp service or less. To spite any change to the rule, I still use #6 solid copper wire for all panels that require earth grounds.
 
Guys I need to first see if/how the automatic N-G bonding function which @houseofancients introduced to me works in my inverter. If that is functional, this question is no longer relevant. I'll check back after I test that.
