    No Fluff Pure Gold, should be the title of this channel! While most of the channels here are focused on glamour, showing off tools or how much they made or gimmicks - this is simply no fat, no fluff, no fancy nonsense. I also love the fact that nothing is left to chance - fool proof.

      Technologies does evolved over time. It help human mankind life better and safe. Only down side RCBO is that, it's expensive. Hopefully more and more manufacturers or other brand could compete each other, therefore automatically the cost will goes down.

    I am glad to be your student. A few days ago, I was struggling to understand this subject. Now it is very clear. Planning to change a 3-phase 63A 300mA rccb to 30mA for adequate safety (by technician). 300mA is a dangerous level. Also, installing a rcbo 1p 20A 10mA for water heater (law requirement). Not explained: rccb type AC & type A. Type A has added protection of pulsating DC leakage currents. Because of having inverter air cond and fridge, some claimed I should use type A rccb. Is it right? Most people are using type AC RCCB & I did purchased type AC. Which should I use? Thanks

      My main rccb in the DB has main isolation fuses, and 40 MCB at downstream. So overall they act like rcbo for each electrical items. But for instant hot water shower, I need to ensure adequate safety protection, so I am installing additional rcbo 10ma for it. New main rccb is 30ma (changed from 300ma). If new rccb is sensitive during lightning, then will install a lightning arrestor in DB.

      Thanks for watching William. We have a video planned for types of RCB. 10mA devices are very sensitive, check your circuit leakage as anything above 5mA may trip the RCD/RCBO. Keep watching and thanks for the support. Dave.

  • @stuartshutt4118
    @stuartshutt4118 2 роки тому

    Not really important but the current flowing in the coils wrapped around the toroid creates a magnetic flux not current (with the exception of eddy currents which are just parasitic losses and not relevant to the operation of the breaker). The toroid can simply be considered as a closed magnetic device where the live and neutral windings act in opposition to create zero magnetic flux and hence create no voltage in the tertiary sensing winding. As I stated at the start, not important to the operation of the devices but we typically do what we can to prevent currents flowing in any transformer core as this simply generates unwanted heat and power loss. Otherwise a great video and judging from the other comments has helped the community.

    I have a question on 3phase RCB. Why doesn't small load imbalance between the 3 phases and neutral not cause the RCB to trip? All phases are not always equal and if the load is perfectly balanced there is no Neutral current. How does it sense the residual current in these cases?

      Two different devices. An RCBO is for just one circuit with inbuilt overload protection. An RCD is just an RCD and can give additional protection to several circuits. Have another look at the video, Dave.

    If a consumer unit is only covered by an rcd as a main switch, would you c2 it as it has no over load protection.

    • @learnelectrics4402
      @learnelectrics4402  8 місяців тому +1

      Correct, it would be a C2 as its not dangerous if there is no fault on the system. If a short circuit appeared, or an overload, then you would need the circuit to disconnect and the RCD on its own might not.
      Take a look at this video on the C codes.

      The switch is just a switch, its not monitoring any current. As long as the switch is rated greater than any current that will pass through it that is ok. If its the main switch, in series with the main breaker, yes, the switch will need a greater switching capacity.
