service neutral splice
Is this an acceptable splice?

Re: service neutral splice
John, Splices are okay as long as the connector is listed for that application. That bolt makes it look a little suspicious to me that is not a listed splice.
230.46 Spliced Conductors. Service entrance conductors shall be permitted to be spliced or tapped in accordance with 110.4, 300.5(E), and 300.15.

Re: service neutral splice
That's not the neutral. That's the ground (messenger wire). The neutral can't be bare. If it is the neutral and the panel is on, I'm surprised you didn't get shocked removing the cover.

Re: service neutral splice
Richard, That would be the neutral in an SEU cable assembly. Which can be used up to the main disconnect. At the main disconnect the ground and neutral are bonded. If that was a sub panel then it would be incorrect. Also I think that is referred to as a concentric neutral.
Any sparkys want to jump in and make sure I am correct.

Re: service neutral splice
Here is a description from southwire-
CONSTRUCTION
Southwire Type SE cable is constructed with AlumaFlex AA-8000 series aluminum alloy, compact stranded conductors. The conductors are covered with a sunlight resistant Type XHHW-2 or Type THHN/THWN-2 insulation. A reinforcement tape is wrapped around the conductors for added strength and conformity. A gray sunlight resistant polyvinyl chloride (PVC) outer
jacket covers the entire assembly.
Style SEU cable has two phase conductors surrounded by a concentric neutral while the SER style has two, three or four phase conductors and a bare neutral.

Re: service neutral splice
Don you are correct it is the neutral wire of the cable. I was thinking about a sub-panel.

Re: service neutral splice
In my opinion a spliced neutral should be treated the same as a spliced grounding conductor - the spice should be irreversible.

Re: service neutral splice
Aren't almost every overhead service wires spliced outside at the weather head anyhow?

Re: service neutral splice
Yes, butt (pun intended) service cable to service drop splices are not required to be irreversable.
At least in MI.
Also, grounding conductors are not required to be permanent as stated a few posts above. I hope the poster meant to state 'grounding electrode conductors' are to be permanent and irreversable.
