I second that, GET AN ELECTRICIAN to help you out as you obviously know nothing about running an electrical supply. Here in Ca. every year there are dozens of houses and structures burnt to the ground because somebody thought they knew what they where doing. Electricity is DANGEROUS to mess with if you have know clue.

Also if you did build it and it caught fire, the insurance company will NOT pay out for damages from bad wiring.

Do you know how to figure total load reqired for your setup?
Do you know what your available max load is?
Do you know what minimum wire sizes for distribution should be?
How far away is the nearest breaker box? And do you have enough extra current availabe to wire up your grow room or will it overload the system? Can you figure it out?

GET SOMEBODY WHO CAN DO THESE THINGS.

Its all about safety.

to be honest if your gonna be using that much power in an outhouse type building your gonna attract some suspicion, you need to work out how much power draw your going to be using then check if your home breaker box can take the extra power draw, if not you will need to get a seperate breaker installed. you would be looking at a few hundred for the job. over the 500 mark though if you want a decent install. try to use a local guy rather than a nationwide company as they will ask less questions. use the converting to a laundry room/larder excuse as there would be a lot of high power electricals going into a room like that i:e: fridge/chest freezer, washer/dryer, wine cooling cabinet.

good luck with your venture...... happy growing

If u have the know how....run new wires from the box to the shed run 2 120 lines on 20 amp breakers and each line put a 4 plug box in for each line it should work I run 2 1000 s a dehumidifier inline fan regular fan and heater with no problems ...
or run a 240 volt line out there to a sub panel and run ur outlets from the panel at shed....

Can u c the line coming in it might be piggy backed, ur line probly comes to ur double socket and pig tailed of to a single socket, I re- read ur post with all those sockets I would run 240 volt line to a sub panel and run ur plugs from the sub panel at shed will be the safer bet imo

your better doing what method2mymadness said. runs a 240 line into a seperate breaker in the shed and run as many sockets as you need in there. 3 doubles should be fine for you setup but its better to have more then not enough. go for 4 doubles
