How to select and Install MCB (Micro Circuit Breakers) for Home

You need to check out your local regs!! You will need breakers for lights (depending on regs, you may need a breaker for each floor!), sockets, water heaters, kitchen sockets, oven, etc...... So I suggest you make yourself familiar with your local regs and follow their recommendations! You may also find that it could be classed as illegal if you do any work on your own wiring, so I would also look into that! Electricians have insurance to cover an installation (IF PROBLEMS ARISE WITHIN A CERTAIN TIME LIMIT!!) You don't!! So if you screw it up and have a fire, it's all your fault and you won't have a home! If I was you, I would help the economy and let the professionals do the job thy are trained for!

Hope that helps!

i m assuming you know abt basic electrical engineering..... learn abt mcb ratings through google.........after knowing abt them check out this link http://cr4.globalspec.com/thread/53500/Advice-for-Circuit-Design-for-Cafeteria

Instead of cafeteria consider it to be ur house......don consider the ampere ratings of the cafeteria.......your house requirement will be less than tht.....consider the voltage ratings appropriate to your house....you will get an idea ....don consider the ratings of cafeteria......
