#8 Bonding Conductor

Hi guys , I have a #8 solid bonding wire used to bond nocurent carring metal parts of an inground 'Baptismal Font' (pool/hotub). The installation was approved by our local AHJ. But the approval was only for acceptance of bonding metal parts underground. The wire is protruding from the ground just enough to bond the pump motor and a heater. I just found out that our designer would like to add another heater - so that the pool will heat alot quicker. My question would be -- Does the NEC require this conductor to be continous (unspliced)? And if not how would I splice #8 in an approved manner short of welding it to bond the other heater? (never ran into this type of situation). :(

Thanks , Mike--Romeo, MI
 
Re: #8 Bonding Conductor

I do not believe the NEC requires the bonding conductors used for equipotential bonding of noncurrent carrying parts to be continuous and any method as described in 250.8 should be approved for connection of additional conductors or equipment.
 
Re: #8 Bonding Conductor

Not sure, but using non-reversable crimp splices listed as grounding/bonding equipment also satisfies the code for being continuous.
 
Re: #8 Bonding Conductor

Is there any reason you can't use a split bolt bug ? Just run the new # 8 solid over to the point where it gets attached to the first heater, cut back the insulation and clamp it on there. Of course, now you'll have a problem with neatness and a workmanlike installation, but that's your call.

THANKS>>> Byan

I'm going to refer to NEC 250.8 and continue the #8 solid copper Bonding conductor. This will take place with a listed non-reversable splice.

Mike :D
 
Re: #8 Bonding Conductor

680.26 does not require that the bonding conductor be continuous as it allow's use to use the steel of the pool walls as part of the bonding conductor as in 680.26(D)(which requires 250.8 to be used) and it also require's this:
680.26(C): Connection shall be made by exothermic welding or by pressure connectors or clamps that are labeled as being suitable for the purpose and are of stainless steel, brass, copper, or copper alloy.

Which is close to what 250.8 say's

Re: #8 Bonding Conductor

I agree with Wayne entirely, there is no NEC requirement for a continuous bonding conductor.

Just as Wayne has mentioned you may use the metal components of the pool as the bonding conductor. :)
 
Re: #8 Bonding Conductor

Bonding is the "connection", for pools, hottubs and jacuzzis it is not required to be continuous.

The two places in the NEC that I am aware of the conductor required to be continuous is for the GEC, and the MBJ.
