1.Minature Case Circuit Breaker------M.C.B---[I'd say it as a switch if you agree].
2.Moulded Case Circuit Breaker------M.C.C.B---[Also can be used as a switch but with a function of protection by automatically closing circuits when overloading or short-circuit occurs].
3.Earth Continuty Conductor------E.C.C---[example: 4C*120sqmm cable+ECC 1C*70sqmm earth].
4.Luminaire=Lighting Fixture---[it specifically means a complete electric light unit and is often used in electrical work BOQs]
5.Residual current Device------R.C.D---[in Chinese it is commonly known as 剩余电流动作保护器,and we often use residual current circuit breakers (R.C.C.B) or earth leakage circuit breakers (E.L.C.B) to prevent electrification and electrical fires caused by short-curcuiting in L.V indoor environments,see in our sites].
6.Air Circuit Breaker------A.C.B
7.Power Box and Feeder Pillar---[it's the same stuff which is a cabinet for electrical equipment, mounted in the street and controlling the electrical supply,the only difference between them is power box is known in United States and the other in Untited Kindom].
8.Switchgear---[mainly includes circuit breaker,disconnecting switch,load-break switch and fuse].
9.TPN---[Tripple Pole(TP)+Neutral which is three phases and neutral].
10.Muiticore copper stranded conductors---[Armored to XLPE (Cross linked Polyethylence)/SWA (Steel Wire Amour) insulated and PVC sheathed].
Okey,this is not the end,there will be more~~~
