Electrical Circuits

where can i build advanced electrical circuits?
I want to find a website that will let me use or download software without charge where i can build advanced circuits with cables e.g 2 way switches, properly Wiring lights with twin and earth or single cables, wiring socket rings etc
Just Google DIY electrics – theres tons of sites from basic to advanced.
I started learning about electrics with a book called The Collins Complete DIY Manual – covers basic and advanced circuits.
Regulations state that those sort of jobs can only be done professionally by qualified personnel. DIY work isn’t covered by the regs.
