i just got off the phone with southwire. ??? states that UF can be used in water wells all the way to the pump. He also says submersible pump cable is a marketing tool. SPC will give you protection from gas and oil where UF will not, so if you are in good well water your ok, However most inspectors think the wire has to be stamp for a certain use such as wells. That is why the wire has codes on it so you can look up its allowed use. The other issue i seen that i think is no problem is the bare ground. When you test the Sub pump you will find the pump shell is exposed to the water and is connected to the ground, so does it matter that the ground is not double insulated? Some of the old well casings are metal and many new wells have plastic casings but you still have a ground. my way of thinking is that uf has better protection from nicks vs the other cable. i have seen many times where the twisted cable has rubbed the casing and shorted out. So why pay double for for a marketing tool! if the uf wire is the same other than protection from oil and gas
