What do you think about this pic?

[Charley L. Bottger]

I see a lot of panels here with splices like that where Al was used as the main feed with squeeze connections to copper pig tails so that Al does not have to be under the screw lugs

Neutral Bonding Jumper. This would be a good time to talk about the neutral bonding jumper. ... The neutral and the ground can only be bonded in one location in a residential service, and that is in the main panel
Hope I am talking about the threads question.

Are you saying this applies only in a residential services, meaning it would be permitted in other installations?

Why has nobody mentioned that the main feed wires aren't even spliced?

[ROBERT V. YOUNG]

Post #4 but I used the wrong terminology.
That was my observation. 16 or 18 gauge wires with spliced wire connectors.
Were splice wire connectors allowed in a electrical panel. ( I called them merretts. ) manufactures name.
Why where terminal splice connectors not used on the 4 awg.., or are they not allowed in a panel

That main feed 4 awg splices should have been done outside the panel in a separate enclosure and then new 4 awg feed wires run from that enclosure onto the new pannel.
Any one have any links on this?

Now follow my blue pen on the red feed . The main lead avoids the main shutoff breaker and goes to a doubled up120 or 240 breaker. Is this correct, complaint?

Are the split bolt connectors under that tape?

The way I see it the conductors come out of the meter and terminate in the main CB. The splices are for a feeder originating at the 2-pole CB on the top right.
