hello
i want to practice a few circuits on a board at home.
just want to practice a simple ring circuit with maybe 4 sockets.
mainly i want to practice wiring up lighting circuits-
with 2/3 ceiling roses, two way switching, intermediate etc etc-different combinations,
want to practice with single core and twin+earth.
i have all the bits i need.
just wondering if i can power this with a battery.
i really want to power the circuit,so-
other than going from the mains,what kind of battery can i use,if at all.
what type of battery,size,voltage etc, and wheres the best place to get them.
also,has anyone any links to online guides/vids on how to do this/set it up?

im a novice,as you may of guessed,so all advice appreciated

cheers

A mains-powered low voltage supply will be safer, a dead short across a large lead-acid battery can make a big bang. Don't forget to include fuses in the appropriate places.

KinHeck !! Buy a multimeter and learn how to use it, and you don't need power.

Very true, but I think he wants to see it working.

You can do this using a 9 volt battery and a lamp holder and a 9 volt lamp.

Normal light switches wired using virtually any cable and the 9v battery and lamps will enable you to practice the lighting circuits.

three way switching

two way switching

Mooncrap's way is better.

Then, if he makes a mistake it might catch fire like it would if it were a real installation.
