Dreaming about severed arms could simply mean you are feeling powerless, unequipped to deal with something. Since our arms are much of what enables our actions, and your dream is recurrent, involving members of your family without arms, it could also mean you see your family as powerless, unable to cope, ill equipped.
Residual Current Breaker with Overload protection (RCBO). A RCBOs combines the functions of a MCB and a RCD in one unit. They are used to protect a particular circuit, instead of having a single RCD for the whole building. Generally these are used more often in commercial building than domestic ones.esidual Current Breaker with Overload protection (RCBO). A RCBOs combines the functions of a MCB and a RCD in one unit.

However, and this is where many people get confused by this, a standard RCD does this by electronic determination of the load current via the detection circuitry unlike the MCB's and RCBO's. The torus forming the heart of the RCD has a small detection circuit attached to it via an op amp.or what it is worth, I have noticed lately that a number of manufacturers have started refering to Larger DC Sensing RCD's also as Main RCBO's, I suppose this is an attempt to clarify the whole situation and to ensure that Installers pick the correct protective device. securespark said:
