Bonding wire for new motor question

[CarrolltonTXPool]

I had to get a new motor. Need to attach the bonding wire. But it’s not long enough now.

1. Do I just need more wire, #8 copper and a copper color bolt? And just snip off the connector that lets it be screwed to the motor and get a new one for the new piece of wire?

2. I attached a picture of the new motor. Do I attach the bonding wire to the goldacre at the bottom of the back of the motor?

3. Is it safe to swim until I do the repair if the power to the pool is off at the master on/off switch on the pad?

Yes you want a split bolt from any hardware store. A split bolt allows you to add on the the existing bonding wire anywhere in-line without cutting. I just picked up a two pack from Home Depot for size 8 wire for less than $4. Size 8 wire copper solid. Attach to the lug in the photo below and the split bolt to the existing bonding wire and you are good to go.
As far as swimming with the power off I'm not an electrician but would "assume" you would be fine.

Swimming with the power on or off does not make a difference in safety for the bonding grid. Electrical equipment can have stray currents with power off.

Ok thanks. So all I need in addition to the wire and the split bolt is a connector like this picture to crimp on the end of the new wire so that it can go under the screw on the motor?

I would just make a loop on the end of the wire and wrap it around the screw on the motor. Some motor/equipment attach points allow the wire to be slid in next to the screw without the need for a loop. Be sure to clean the connection point on the existing bonding wire - maybe with a scotchbrite pad - to provide better conductivity. And use a copper split bolt for that connection.

Ok sounds good. Headed to Lowe’s to get the parts now.

how does this look? Want to make sure it looks right before I bury the wire back under the rocks.

Looks good. You might want to tighten the loop on the grounding lug of the motor.

I’ll try and turn it some more. Was worried about stripping it. I see where it looks loose but I tugged on it and it’s pretty tight.

I'm thinking avspin means wrap the wire tighter around and onto the connection post (close the loop behind the washer) so if the screw simply loosens it will not work its way over and off.

Yup.

Note that you should wrap a wire clockwise to match the direction that you turn the screw to tighten.

The bond lug generally is designed to take a straight wire without a loop.

However, in my opinion, the type of lug that came with this pump is poorly designed and a loop helps to keep the wire secure.

Ah, ok I got it now. I’ll do that this weekend, and wrap it clockwise like James mentioned. Thanks all!

This. As you tighten the screws when wrapped clockwise, the wire doesn’t try and walk away
