I recently purchased a farm house. In the deal a Square D Homeline main panel “new in the box” with 20 breakers was left with the house. My question is one of review and opinion. Are the Homeline panels good? Should I take advantage of getting the free box and install it or I am selling myself short? Should I look at buying a different panel?

Square D HomeLine is a fine product. You will have no problems with it.

Agreed, Maybe use a NO OX type product for connections.

Do not misunderstand, NO Ox is an anti oxidant compound that must be applied to any connection in any panel, breaker, etc. when aluminum wire is installed. Not just HomeLine products.
