"Main sockets" is referring to fuse sockets, particularly the main fuse sockets for a fuse panel.
This question may be asking if it is safe to plug things into mains wall sockets if they have been left switched on with nothing plugged-in, and if it is safer to plug things in only after the sockets have been switched off? If, and only if, that is the meaning of this question, the answer is probably: It should not be dangerous to plug something into a switched-on socket but it is always a good idea - and safer - to switch off any socket before you plug anything into it. +++ The hazard is not in the plugging-in, but may arise from the appliance itself, if it starts unexpectedly.

Usually,there are many mains sockets in a flat to provide electricity for electrical appliances.Do you know how these mains sockets are connected to the electric cable that carries electricity to the flat? The electric cable that carries electricity to a flat is connected to the consumer unit.In the consumer unit,the electric cable branches into a number of parallel circuits that deliver electricity to ceiling lamps,mains sockets,air conditioners(or other appliances with high working current),etc.The circuit that delivers electricity to main sockets exists in form of a ring and is therefore called a ring circuit. The ring circuit provides two paths for electric current to flow from the consumer unit to the mmain sockets.Each path only carries half of the electric current.Therefore,the chance of overloading the circuit is reduced.Besides,if one of the paths is damaged,there's still another path for carrying electric current.
