Vintage metal kitchen cabinets
Just out of curiousity... My house came with newer particle board kitchen cabinets in the kitchen, but in the garage there were 3 base cabinets and a wall cabinet from the mid-50's that are Youngstown all metal cabinets.
My wife would never go for something vintage no matter the condition, but I might use them as workbenches in the garage unless by some miracle there was someone offering decent money for them.
My question is this: I'm assuming that if these were used in a kitchen, it would be prudent to ground them. Does code require this under any or all circumstances, be they in use in a kitchen or any other location?
Please do NOT consider any "before" picture of my house as any kind of endorsement of any particular construction method. In fact, you should probably assume that if I post a "before" picture, I am posting it because I am soliciting advice on a proper replacement for one of MANY things done wrong by a previous owner.
