wiring for 3kw lights + fans and a/c? - Growroom Lighting - International Cannagraphic Magazine Forums

hi people

i'm putting two flower rooms together to make one big room. i'll be running 3kw of lighting, plus fans and a/c. i'm currently drawing my power from 4 different sockets, but i want to get this done right, finally, and have all power from one board.

i want to install the necessary board in my garage in order to run the power out to an out-building.

i'm totally happy to get an electrician in to do the work, but i need to know what work needs doing. can anyone tell me what i need to know in terms of parts, the extent of work required, approx cost, and any good excuses.

i'm in uk with 240v in a house.

thanks for any help people. i couldn't do it without you!

well if your so cal u can hire an electrician pretty fast and easy with no excuses asked placed anywhere u want the box!
Basically u need to hire an electricaian and tell him to run u a 240v 50/60 amp sub breaker box to your room so u can hook up your new indoor Jacuzzi!

thanks man. i plan to run power out from this breaker box to a shed. i don't want him in my shed! if he did as you suggested and put the box in the garage, how would i then get the power out to the shed?

would this breaker box have sockets, or outlets of some sort? please forgive my ignorance in this matter. i've done some research but can't find the info. sounds like you know what needs doing. thanks man.

im not a electrician but have some experiance.

you could add a breaker in your existing breaker box. 2 30A breakers would be good. 50A breakers have bigger wires and are harder to work with.

if you already have power in the shed you just need to pull the wire from your house to the shed. you already have pipes under ground to pull the wire.

a good excuse would be to say your powering a soon to be pool or jaccuzi. or that your running a computer server.

Do ya'll use ring setups in the UK for your power? You're getting alot of advice for North American wiring, so take it with a grain of salt if you're on a ring main system.

You could have another 30a ring circuit or a dedicated fuse/trip and cable run installed to the outbuilding, but it's going to require the sparky to have access to the building.

I'm not sure what the outbuilding looks like, but you could always tell the sparky that you're going to use it for a workshop as a reason for having the circuit installed. I would guess that you're looking at £200-£300 to have it done over there.

Unless a certified electrician from the UK steps up in this thread, I'd say move all the stuff out for a day to a place in the house and let the electrician take care of it...it shouldn't take more than a day to have everything installed.

Just have him wire up the shed and tell him its a 'workshop', and you want to make sure you can safely run your bandsaw and several other power tools at the same time. Youd rather have lots of headroom than overload the circuit. :wink:

I was going to suggest the workshop excuse, possibly with the addition of the phrase 'arc welder' to explain the desire for two 30 amp circuits.

lookie you can ghetto it semi or do it pro...

pro..install a new breaker dedicated to timer boards via cert electrician and cert timer boards...or do as you are doing one line to each timer...if you have good timers for hi-amp inductive load (expense) and enough amperage at the serving panels..then nuff said..you need 5 amps per 1k...plus... 25% leaway at the breaker...an AC uses about 6 amps at 240v per cooloing ton...sooooo...do da math....id service the AC with extra amps and individula breaker cuz start up efficency (dubs to trips amps) is fuck all and the AC commonly swithes on/off over the day.....

oh missed the question 175 pounds..minus any necessary permits...do a contract..

youre paying him

if he asks the wrong question

hes gone././its for a clothes DRYER....but someone who asks insistently..shall he be assed canned past the small talk..just find the timer line style...and say i want and outlet for such n such...iyts essential to know how your timer ties to the mains..and its prong/hard line style...

so in the end...way too many electricians to spill your morning tea over bullshit...

hell he asks...its for the 'bone drill'...then grin...ball gag in hand...these douche bags put in panels all day...just dont treat em like shit...
