A consumer unit can use an RCD as the main switch. The first of these is to protect any socket which may be reasonably expected to supply equipment outside the house (Strimmers, lawn mowers, hedge trimmers, pond pumps, sheds, lights etc etc). The FE should be connected to the main earth terminal block while the N as neutral should be connected to the main neutral terminal. Generally, there is a 40A, 2-Poles RCD and other related circuit breakers such as 6A, 16A, 32A MCB (circuit breakers) based on the system requirements. Disconnect the power supply (and make sure it is really switched OFF) before servicing, repairing or installing electrical equipment. In the image below, we show the earth cable from the meter (L). The second condition applies to any circuits where an earth fault current is not sufficient to blow the fuse, or trip the switch, in the designated time allowance made in the regulations. %%EOF
If only a small amount of load points are needed to power up through mains supply, they install a garage consumer unit instead of larger consumer units especially in outbuildings. It is because split load consumer units provide protection against overload, overcurrent & short-circuit and earth leakage. A garage consumer unit is used to feed up fewer load circuits (generally 2-5 units). A dual RCD consumer unit can be fitted. These boxes can also be fitted with cartridge fuses or miniature circuit breakers (MCBs). This protects all areas including showers and cookers, but if one trips the other will ensure at least some lights and some sockets still work.
