safe

A safe (also called a strongbox or coffer) is a secure lockable enclosure used for securing valuable objects against theft or fire. A safe is usually a hollow cuboid or cylinder, with one face being removable or hinged to form a door. The body and door may be cast from metal (such as steel) or formed out of plastic through blow molding. Bank teller safes typically are secured to the counter, have a slit opening for dropping valuables into the safe without opening it, and a time-delay combination lock to foil thieves. One significant distinction between types of safes is whether the safe is secured to a wall or structure or if it can be moved around.

    Safe or not? (see pic.)

    Hi all, I hope you're very well. (The switch goes to a 10W LED) Is the above wiring going to be safe please, especially given the way the ring main is treated at the top of the picture? (You might wish to leave aside any UK regulations as the above scenario is in a different country)

    Intrinsically safe circuits
