This is an open *3-phase electrical distribution board* 📦 The image contains two parts: *1. The box on top:* - It has *4 copper breakers* called Busbar. These distribute electricity to the loads. - Red, yellow, and blue wires = 3 phases. - Green wire = Ground / Earthing. - Black wire = Neutral N. - The small white breaker on the top right, labeled *FMM C63*, is a 63 Ampere sub-breaker, likely for an air conditioner or a large load. *2. The box on the bottom:* - It has a *main MCCB breaker* labeled *ELETRA 100A*. This disconnects the electricity from the entire board in case of a short circuit or overload. - Its current position is *OFF*, meaning the electricity is disconnected. - *Very Important Warning:* The board operates on 380 volts, 3-phase electricity. Touching it without understanding can be fatal. If you want to modify or inspect anything, you must disconnect the electricity from the main breaker outside the house and bring a licensed electrician. Do you want me to explain the function of each wire and how to know if the connection is correct?
