Circuit boards, how to build ?

Get one off ebay mate, by the time youve brought everything you need and the time you spend wiring it youll save yourself a few quid....i got one off ebay for £50 and its fine

First of all, what I do know, is there's a 50% chance or even higher if you do this, espically from asking questions where loads of new growers only asked questions, and u are asking them about messing with ur home electrical system, are u crazy mate!!!. And for starters I'm telling you. You are going to cause a major fire. That many plug sites alone is crazy, they should be all contact to source unit for even trying to attempt what u are going to do. Even all the help given in the world doesn't quality you for what you are trying to do. It only cost 2-400$ to get done depending where you live and if you get a list and sort the parts yourself. And just pay for set-up it'll be less. DO NOT TACLE THIS YOURSELF PLEASE

You need to install a 100 amp breaker in your electrical box. Run some wire that can handle the load to your socket box. You still need to count your amps your going to plug into you sockets and don't overload the breaker with your appliances. Like others said. If you don't know what your doing, then don't do it.

I had a big answer typed out, but after thinking about it, if you do not know what you need, you either need to: A) Find someone who knows what they are doing to be there when you build it B) Hire someone to do it or buy a pre-made one Or C) Do more research. Electrical can be dangerous/deadly if done wrong. There is a fair amount of knowledge required to do it correctly. I would feel like an asshole if I helped you burn your house down, or worse. Something stupid like not running the proper gauge wire = fire Running over 80% of max amps of a breaker is apparently also a bad idea Forgetting to switch off the breaker before doing shit can be death. Lots of little things can cause big problems. Honestly if it were me I would watch electrical wiring videos about the thing you plan to set up (pretty sure I've seen a few on youtube), read about the stuff you need to know ((amps=watts/volts) make sure your circuit max amps is less than 80% of the breaker amps, make sure your wiring can support the current you are running, wiring diagrams etc..) and then talk to someone who knows what they are doing about your plan and see if they have input or advice.

Call an electrician. Don't fuck with that stuff if you don't know what its about, that's how fires happen.
