Our panel view 1000 is powered by 230VAC and is safeguarded by a 16A type 2 MCB. Upon the initial power up of the MCC, the MCB trips and must be reset manually. What type of protection mechanisms do you recommend in this situation?
Do you know the model number of the PanelView? Have you consulted the manual to determine the suggested fusing and trip curve? Additionally, make sure to inspect the wiring going into the meter for any loose strands, as this has been a recurring issue for me in the past. - James
It sounds like the initial surge of your MCC might be too much for your 16A type 2 MCB. You might consider either using a type C or D MCB which can withstand higher surge current, or implementing a soft start mechanism for your MCC to limit the inrush current at the time of start-up. It's also worth checking the rest of your circuit to ensure there's no issue causing the excessive start-up draw.
It sounds like your MCC might be drawing a large current at startup, causing the MCB to trip. You might want to consider using a type D or even a type K MCB instead of a Type 2. These types are designed to handle higher inrush currents without tripping. Another option would be installing a soft starter, which can control the ramp up of current, thereby preventing initial surge. It's important, however, to first determine the actual cause of the tripping - be it an electrical fault, a short circuit, or indeed an inrush. Consulting with an electrician or electrical engineer would be a wise step to ensure safety and system longevity.
It sounds like you're dealing with an overcurrent situation during startup. You may want to consider utilizing a motor circuit protector (MCP) that can handle the high inrush current during the powering up of the MCC. The MCP, when properly sized, would allow for the high initial startup current without tripping, while still providing the necessary protection for overcurrent scenarios. Additionally, investing in an inrush current limiter could solve the problem by reducing the initial surge of current.

Answer: - The MCB is tripping upon initial power up possibly due to an overload or a short circuit. Further investigation is needed to identify the exact cause.
Answer: - It is recommended to check for any overloading of the circuit, ensure proper wiring connections, and inspect for any short circuits. Additionally, verifying the compatibility of the MCB with the load requirements is crucial.
Answer: - To troubleshoot the MCB tripping problem, you can start by isolating the load, checking for any loose connections, testing for short circuits, and verifying the load requirements against the MCB rating.
Answer: - Manually resetting the MCB is a temporary solution, but it is important to investigate and resolve the root cause of the tripping issue to ensure safe and reliable operation of the panel.
