I have always worked with and use #6 and #4 for grounding and bonding (required by the NEC). I prefer #4 solid copper.I can’t imagine unspooling and working with solid #6, which would be the grounding conductor for a 200 amp residential service.
Agreed, real life always beats a theoretical ideal.But only above ground and not outside the home in the weather.

Yes, I regularly report broken (typically stolen for the value of the copper) ground wires at wooden poles.Ever go look at the ground wire on a meter on a house or on a power pole?
They are typically terminated to a ground rod at the base of the pole, with the connection being above ground.
We needed a grounding cable for use at fibre-optic cable splice vaults, to run from the metallic sheaths (two per cable) of the two fibre cables out to a pair of ground rods (via an above-ground test station). Therefore, we needed a ground cable with four conductors.I have never seen a grounded meter base.
I can’t speak for the high voltage applications, but typically Romex wire is stranded when it’s smaller than #10. I have seen solid on wooden poles and stranded on the steel poles though.

That's clever - I wonder whether that's been tried here?That's interesting--what they seem to in the USA is to coil the ground wire up at the base of the pole, attached/stapled to the bottom of the pole. They don't use a ground rod. This way seems better--no separate ground rod, no connection needs to be made, they just need to staple the ground wire in place before setting the pole.
EDIT: It's always solid wire, too. I have never seen stranded ground wire used on a pole.
It is a grundfos, not sure of the series, powered by a Franklin mono driveIs it a Grundfos SQE pump?
I installed a surge protector on the SQE control box in the basement, in the circuit between the control and the pump.. The surge protector I used is a GE Tranquell which mounts into a knockout and has 3 wires, two hot and a ground. Similar surge protectors are used with air conditioner units and one of those would work fine.
At the well end, I used a well pump surge protector, again with 3 wires, two hot and a ground. This surge protector was small enough to fit inside the junction box on the well casing sticking out of the ground.
Never had an issue with lightning.
Now you've got me thinking... Not sure I've ever seen a ground rod around my pole or house.I had problems with power surges from lightning strikes knocking out equipment (not my well pump). The last repairman suggested I check my ground rod that connects to the power meter. Sure enough when I dug a foot down I found that the idiot electrician that installed it just buried the ground wire with no ground rod. After I drove an 8 ft ground rod and attached the ground wire I have not had any more problems. I also had the power company install a surge protector at the meter so that helped also.

I think Laganobob is talking about 2 phase vs. 3 phase electricity, while you are referring to the number of submersible well pump stages, which can be anywhere from 5 to well over 20.
@ The-Eric, I just replaced a Franklin VFD on my workplace irrigation well for just over $4,000 (ouch).
Off Topic: We also had to replace the well pump and pipe (100') for severe corrosion after only 13 years. We think it might be from severe hard water and/or some sort of electrolysis/stray voltage was occurring. The new pipe is pvc, with a doohickey that prevents pump torque twist. This replacement work cost more than the entire well install 13 years ago. Yes, inflation is wicked
Smaller number. Larger wire. My bad.I have always worked with and use #6 and #4 for grounding and bonding (required by the NEC). I prefer #4 solid copper.
I have never seen stranded Romex in #12 or #14?
