Hello
I want to run a attached garage sub panel off of a house outside breaker box. I want to use 2 inch emt Along the outside of the house but there is no opening on the box.

My question is , can I put a 2 inch hole on the side of the box near the bottom to allow me to run the emt ? Of coarse using watertight fittings .

Thanks for the help

It's code compliant only if you use a Myers hub and rigid conduit. I'd do it in PVC.

EMT is legal but need compression fittings and a entrance hub. PVC is the best option.

A penetration through the side of the box, below the height of the internals is fine. No Myers hub required.

You can probably get by with a much smaller conduit that would be less obtrusive.

I was worried about using pvc due to me being in Arizona . Was worried about the sun and high heat during the summer since the conduit will be run on the side of the house.
Was planning on using 1-1-1-3 SER cable to supply a 90 amp sub panel.
The garage walls are open 2x4 right now but will be covered later.
How would I run the cable in the outside wall to the top of the sub panel ?
Keeping the cable enclosed. I can’t seem to find any fittings that would turn 90 deg. In such a short distance from the outside to the top of the panel if it is flush mounted or surface mounted or does it need to be enclosed once it enters the wall since I will be insulating and putting plywood on the walls ?
Thanks again for the help

Do not use SER in conduit. It is much to hard to pull and bend in conduit. Additionally, a much larger conduit would be required.

If you use SER you don't need conduit. I recommend you use individual conductors and size the conduit based on the size and number of conductors.

You also do not need to come into the top of the panel.

Agreed wholeheartedly.

They’re just trying to save you a couple bucks. EMT is top shelf for your
locale.

Cable OR conduit

In conduit run individual THHN or XHHW wires. H-H-N all the same color mark em with tape. The EMT conduit is the ground, woot!

THHN or XHHW lets you run 75C ( still limited by terminations) so welcome to 100A land! (We're talking aluminum right? #1Cu is good for a lot more still). Or you can go down a wire size if you'd rather, and save some coin.

DO NOT save coin on the subpanel. Splurge on spaces here - spaces are dirt cheap, and running out of space is a huge, expensive project killer.

The garage walls are open 2x4 right now but will be covered later.

You can do it with conduit bodies, but they must remain accessible forever, so can't be buried in the wall. Individual THHN/XHHW wires won't have any trouble making those turns. Cable will probably be too balky.

Thanks for all of the help.
I have decided to use 1.5 emt with individual alum. #1 xhhw wires.
I have everything figured out but one thing.
Once I turn the wires into the inside of the garage with a body ,what fitting would I use to drop the individual wires into the top of the sub panel?

Thanks again

This will depend on the space available and how you need to route the conduit. You may need an LR, LB or LL.
