Heres a few pics of a before and after subpanel upgrade & move. I started this yesterday, and finished today.

Before: [had to be moved for clearance reasons]

The J-box I put in the attic to continue new circuits and feed to new panel on the other side of some fixed stairs. THe old feed is piped in the bottom.

The circuits wired, and our new 2P circuit added.

You sure? You installed a 40-space 100 MCB panel and only needed 13 spaces?

Edit to add: Did you ask for a code reference in their requiring the main?

Not pickin' you apart.... this is just what jumps out at me first.

Yeah, I am quite sure I installed a 100A MCB in what used to be a 225A MLO panel. The customer is paying for the upgrade, why not give them a panel that has more spaces in it? They are adding a 2nd floor some time next summer and the customer appreciated all the space for upgrade.

I did not force the matter for the requirement of the main because the inspector let me add this job to a previously opened permit, therefore making it so that I didnt have to pull another permit for this. OTherwise I would have fought it.

Gotcha. I just kinda knee-jerked when I saw 40 spaces. So this is a sub-panel then and not the service?

Again, I'm not busting your chops, just that's the way my mind works.

And kudos for having enough pride in your work to show it off.....;)

Curiosity only:
What kind of connector is used with the armored cable in the J Box?

That is a twist in connector. it basically has 'threads' on it and threads into the FMC, then has threads and a locknut on the other side.

thats because I didnt run one all the way to the panel. There is a bus bar in the j-box with all the grounds tied together then the j-box and the panel are tied together with the ground in the romex.


The run was 20' Anything longer and I probably would have use SER.
