Electrolysis, circuit NM wire laying on water Copper piping.?

Can a Electrolysis be created by laying an insulated NM circuit wire on a Copper water pipe, in a residential home. I have some circuit wires in contact with the Copper water lines within the walls of my home. Just wondering if that could cause electrolysis, because the meaning of electrolysis states two uncommon metals coming in contact not an insulated wire in contact with copper water piping. And if there is another name for the type of electrolysis it causes that would be much appreciated, and where I can find the information.
All of this because my electrician will not remove the wires from the copper tubing, and my plumber says it will cause electrolysis and ruin my anodeless rod inside the water heater, reducing the life of water heater.
Well any information or websites that will help me prove the term electrolysis in reference to my situation will be much appreciated.

For electrolysis to occur you would need an electrolyte, this electrolyte could be simple water. The two metals would have to be bare and submerged, then electrolysis would be possible.
The second thing, since the wire and pipe are both copper, there is no differential potential. There has to be two dissimilar metals and an electrolyte for the chemical reaction to occur. If there is no path between the two metals,meaning direct contact, or contact through an electrolyte electrolysis cannot occur.
Since the wire is insulated, and not underwater (hopefully) there is no contact, therefore electrolysis cannot happen.
The other chemical reaction name you may be looking for is “Galvanic Action”, this is where, again two dissimilar metals react as described above and one is intentionally “sacrificed” as it is less noble to protect the first metal, as in the case of the anode in your hot water heater. The anode corrodes away instead of your piping.
So, short answer, as long as bare metal is not touching, and the two metals are not submerged in some sort of electrolyte, there can be no electrolytic condition.
