Bond Wire on Swimming Pool Pumps

[IRCS]

I'M CONFUSED! - I see many swimming pool/spa pumps that have a light gauge bare copper wire attached to a deteriorating exterior lug. Shouldn't this be a #8 green wire?
Thanks

It should be #8 or larger, but may be bare.

And just to mention, it's not (necessarily) an EGC.

The Equipotential Bonding wire is required to be a minimum of 8 AWG, Solid, Copper.

If you can find insulated #8 solid copper it is acceptable to use but not practical since it will not pass through most of the lugs provided.

There is a separate place for the EGC. The exposed lug is for the bonding grid.

I've never seen anything larger than #10 that was insulated.

Back in the 70's is was common to see #8 solid insulated THW conductors installed in raceways. I'm not sure when the NEC limited the size of solid conductors in raceways to #10.

Thank you all for your replies.

IF not a egc what is it ??????????????????

IF not a egc what is it ??????????????????

An equi-potential bond, assuring there are no voltages among parts.

An equi-potential bond, assuring there are no voltages among parts.

And regardless of voltages present, when properly done, the EPB will create a condition that there will be no difference of potential between objects related and around a pool. "Bird on the wire" condition. Demonstrated in video "120V Swimming".
