Home Improvement → Re: Interlock Murray panel

Not too many manufacturers make an interlock for their own panels, but I'm stunned at how many interlocks are available for various panels by aftermarket products: »www.interlockkit.com/

Awfully expensive for a couple pieces of sheet metal, but then again it's for a limited market.

It is expensive, but it's due to the cost of testing so it can be UL listed. Without that, I don't think building inspectors can allow it to be accepted as code compliant.
