Damaged Electrical Box

My electrical box had one of the corners damaged due to a water leak we had. The leak has been fixed but the corner of the box that got wet is rusted out. Inside of the box did not get wet and has no rust but the outsode does and it looks bad.

Can I cut the rusted metal part out and put in a new piece of metal? Or what would it cost to just replace the box?

I don't want to alarm you, but please call in a licenced electrician to have a look at the electrical box (I assume you mean electrical panel). This could possible be cause for concern, as rust in and on wires and their connections will cause arcing and a fire.

Certainly do not try and repair this yourself, driving screws into and around an electrical panel is only asking for problems. People seem to neglect the hazards associated with electricity and with it being one of the most dangerous of any household components, it should be "bandaged".

The idea of the steel box is to contain any arcing or fire from escaping and buring surrounding materials. Also to prevent people from getting electrocuted.

Dont play with it, get it repaired right and sleep well at night knowing your electrical system is sound and wont start a fire in the middle of the night or during the day when no one is home, or worse, with people home.

Google "arc flash" or "human electrocution" and you certainly will understand the huge hazards. One shock can stop a human heart.

Get it repaired asap.

Be sure he provides you with an ESA licensed contractors number and permit notification. All electrical work like this must be done with a permit by a licensed contractor.

There are too many unlicensed people doing shotty work and without licenses and permits, that cause more trouble than good.

Ask for his ESA number and get an ESA inspection for your own safety.

Good advice as usual Robert. I was not sure if it was surface rust or rusted right through... hard to tell from the post. If it was surface rust I would have just cleaned it up and painted to prevent further damage.

Rusted right through, then a replacement is the only option.
