Since the sub panel is only 14 wide i will still have at least 3 of space between it and the main panel as well as between it and the adjacent wall.
Mounting a sub panel to a concrete basement wall.
Tape a one foot by one foot square of plastic sheeting plastic kitchen wrap will do to the concrete wall in your basement with duct tape and leave it in place for 24 hours.
Normal placement of your new sub panel will be down in the basement directly beside the existing electric panel.
Just a drill and a piece of wood will.
The basement is finished but foundation walls are bare concrete electrical stuff is surface ac cable when it needs to provide outlets and devices on foundation wall.
I am showing a cheap trick when you don t want to spend the money on expensive dowels or specialized mounting devices.
Only 1 8 or so but it keeps the moisture out.
And the shorter distance between the two panel means a cheaper installation.
Then remove the tape.
This just makes sense because you connecting the sub panel directly into the existing panel.
As an alternative i could always mount the sub panel on the adjacent wall so that it s facing 90 degrees to the main panel.
I usually use tapcons.
Basement is always dry no sump pumps no moisture coming through foundation wall.
Very low water table area.
