A 15 amp circuit breaker is used to protect a # 14 copper wire which is the minimum size wire that can be connected to a 15 amp receptacle.
Lighting circuits (UK) are fused at 15A. If in doubt, check the fuse/MCB. Unless the 7A device is lighting, connecting it would be illegal in the UK. Don't forget anything else on the same circuit.
MCB = Miniature Circuit Breaker DP = Double Pole
yes. MCB is mono chloro benzene and has one halogen (chloro) attached to the benzene ring.
If an MCB trips you can simply close it and be done. If a fuse blows you need to replace the fuse /fuse wire, not so convenient.
A 40A MCB is a circuit breaker. The surge current limit is protected to 250A 8/s0uS. The limitation capability of a circuit breaker is that characteristic whereby a current less then the prospective fault current is allowed to flow under short circuit conditions.
Only if the sockets are rated for 20 amperes.
A 15A MCB will still trip at 16A, just it will take a long time as it should not operate at 15A. Will usually trip within 10s at 200% overload (C curve) and 1 s at 500%, you need to look at the trip time curve which is different for different CB types (A,B,C or D curve)
TPN is same as 4P MCB TPN means Three Pole and Neutral - four pole MCB. 4P is four pole MCB
TPN MCB means Triple pole Neutral Miniature Circuit Breaker where as SPN MCB means single phase Neutral MCB.
MCB Bank Limited was created on July 9, 1947.
The definition of MCB is a miniature circuit breaker, it trips if there is a line to natural fault. Ill add some extra information about the different types. RCD - residual current device = This is what you could separate you're circuits up with by inserting 1 of these in you're consumer unit (if you have lets say 10 circuits it goes like this... rcd-mcb-mcb-mcb-mcb-mcb-rcd-mcb-mcb-mcb-mcb-mcb-main switch. you see the rcd's control 5 circuits each, if 1 of these circuits had an earth fault on it, the rcd will trip and 5 of them circuits will go off, which means you have to keep tripping in you're rcd with an mcb 1 at a time to see which circuit the fault is on. RCBO - residual current breaker with overload protection- These can be installed in place of mcb's and rcd's, the rcbo is an mcb and rcd in 1 breaker. For example, i have installed a consumer unit full of these, in this case if a circuit forms a fault then its only that circuit that goes off. I hope this extra piece of information helps you along and best of luck. <<>> In electrical terminology MCB stands for Miniature Circuit Breaker.

mcb but cb has 2 and the other one has 3
Many names of organization and companies are abbreviated with MCB. The most famous MCB initials are for Mauritius Commercial Bank or Muslim Council of Britain.
