Bonding lug or wire missing
Metal items and pumps near swimming pools or spas are normally connected with a grounded bonding wire. This is done for safety purposes and generally is easy to correct if they are not bonded.
Pumps will often have a bonding lug to which a copper bonding wire is connected. These bonding wires may come loose or get pulled out and need to be re-connected properly.
Pool heaters, filters and other equipment items that are metal, likewise should be bonded.
Metal fences, pool ladders and other metal items near the pool should also be bonded.
Who to consult? An electrician, a pool maintenance person, a pool technician or a pool contractor.
Bonding is a safety concern, like grounding, and it is wise to have proper bonding. An electrician, a pool maintenance person, a pool technician or a pool contractor often does this type of work.
