The mcb sits inside the distribution box. It acts like a guard for each circuit. If too much current flows, the mcb stops the power. This keeps wires from getting too hot. The weight of a bronze plaque may be roughly estimated by calculating the plaque's volume in inches (height x width x depth) x. For most smaller plaques (under 36" x 30") allow. Section 1 - Nameplates & Small Cast Plaques Section 2 - Cast Plaques Section 3 - Round. A distribution box is a key part of electrical systems in buildings. Inside, you'll find parts like circuit breakers and fuses that protect the system from problems like overloads and short circuits. A distribution box is a low-voltage electrical enclosure that receives incoming power and distributes it safely to multiple outgoing circuits through protective and switching devices such as MCBs, RCDs, RCBOs, fuses, isolators, busbars, neutral bars, earth bars, and surge protective devices.
