What are the large electrical boxes found in yards or alleys?
This is likely a distribution pad mount transformer. These units serve the same purpose as the grey transformers on poles but are for larger electrical loads such as malls, restaurants, department stores etc. For public safety, they are secured with bolts and padlocks that keep the door in the closed position. These transformers are completely safe, however, if the unit is broken open due to vehicle contact, it should be avoided because there are electrical components inside that could cause serious harm to anyone coming in contact with the equipment.
