680.6 Grounding

[mannyb]

If I install a jacuzzi. The EGC for jacuzzi is sufficient? I also see Jacuzzi has a ground lug on motor and heater. is a bonding jumper needed for motor and heater back to equipment bond. ALso if electrical equipment is located within 5ft do these also need to be bonded all together like a pool metal parts? or does it need to have EGC to anything within 5ft?

By Jacuzzi I assume you are referring to a hydromassage tub. That section is covered in 680 part VII -- 680.70
