Pool bond and ground together?

[mark32]

Hello, I just hooked up a pool heater for a neighbor and the bonding lug is mounted to the same enclosure the equipment grounding lug is fastened to. Does this defeat the purpose of the bond? Not only that, but now the entire pool bonding system is now connect to the grounding system in the dwelling. Should I leave it as is?

What would be the difference between bonding the heater in that manner and the way a pump is normally bonded. The EGC and the bonding conductor are always going to be electrically continuous on these because they both terminate on the case or cabinet.

Mark,
If you don't think that the bonding grid and the EGC should be connected together, look at this.

680.26(B)(4)... Where a double-insulated water-pump motor is installed under the provisions of this rule, a solid 8 AWG copper conductor that is of sufficient length to make a bonding connection to a replacement motor shall be extended from the bonding grid to an accessible point in the motor vicinity. Where there is no connection between the swimming pool bonding grid and the equipment grounding system for the premises, this bonding conductor shall be connected to the equipment grounding conductor of the motor circuit.

Thank you both for the responses. What's throwing me off is the FPN in 680.26(a) states "The 8 awg or larger solid copper bonding conductor shall not be required to be extended or attached to any remote panelboard, service equipment, or any electrode". If I'm fastening the bond to the same enclosure the equipment ground is fastened to, then essentially I'm attaching it to everything that's mentioned in the above, at least that's the way I'm looking at it. Thank you for your time.

If you have a bonding wire connected to existing pumps you can attach to that with a split bolt kurney and short piece of #8. If not then bond to ground bar in pool equip. panel.

The FPN was added to this section because some inspectors wanted the solid #8 to be run all the way back to the panelboard. This is not part of the bonding requirement, so the FPN was added to clear up any confusion.

Mark the key words in the section quoted are "Shall not be required to..." This does not mean that it can't be done it is just not required.

The enclosure that the lug is mounted to is probably required to be bonded along with all of the other metal components.

Hey guys, thanks again for the responses. Brian, I did in fact bond the heater in the manner you described, to the bond running to the pump motor with a split bolt. Infinity, after I made my last post I realized just what you've said. Electrically, yes, the bond is connected to the grounding system, it's just not physically run to a panelboard etc, but it could be done just like my friend electricmanscott said. Thank you all for clearing this up.
