Question about wattage, and amps

RedzoneFL · Mar 21, 2013

I am trying to figure out if I have to split up my hydro set up.... 400wat light, fan, and small fan, pump, and hydro set up maybe 750-800 watts max?

Can you give me any advice if I need a larger amp on my outlet

read your ballast, fan, small fan, and the rest of your set ups labels. They will tell you their amp usage. Add that up and then you will know how many amps you are using. make sure you dont go over the amps on the circuit.

110v 800watts 7.27amps
your house should have 15amp recepticles.
you want about a 50% Saftey factor. The more amps you draw the hotter the circuit becomes.
your ok with the load you have on that circuit. I wouldn't put any more load on it.

hit the nail right on the head . Plus think to you use that same circuit 12+ hours a day , day in and day out so its extra strain

uh.. fridge & hot water heater run 24/7 365. IIRC a hot water heater is something around 3,000 watts and a fridge isn't much less than that. It's not extra strain to run 800 watts for 12 or 18 hours a day. And it's 80% max of the rated circuit.

Agreed, many say 20% buffer is ok.. and it is, for brand new wiring. Older wiring I'd give a much bigger % cushion for, unless you really want to risk melting/fire.

You have been officially replied to with my phrase of the day: "You must be smoking some really good shit."

Uh alright don't gotta be a dick about I was just giving a newbie advice not to jack up his wattage on one circuit. Should I point out that most hot water heaters are hard wired into the houses electrical fridges use 240v which can handle larger loads

If the breaker and wiring for said breaker can handle it with the proper NEC % allowed to avoid heating up/fires.. where is the issue?

Totally agree with you on that there is no issue, I was just saying he didn't have to be an asshole about it

Shim is very abrasive. I think its agreat idea to tell a noob not to push it..wanna know why ?

There's a big difference between being an asshole and being frank. Maybe you're too sensitive. Where in my post did I call you names or try to do anything that would come off as being an asshole? Sorry for correcting you. Didn't know you'd get your panties in a bunch over it. Hot water heaters are hard wired but they still run to the electrical panel and still run a ton of watts all day everyday.

I decided to have a company come out and put in a 50 amp breaker, originally I wanted a 240 breaker but everyone I called kept asking "what do you intend to use this for?"

time to break down my tents and everything and move all my equipment in another room so they can do the work. I rather be safe then sorry.

in time I'll be running a 400 in my veg tent and 600 in my flower tent, then fans and motors and pumps, etc.

Trying to see what 1,000-1200 watts will equate to when I run that 24hr.----AHH nevermind be about 72$ a month to run the set up.

Unless they did a complete rewire I wouldn't dare run near 50 amps on the circuit. The gauge of wire in the walls was originally installed with whatever amp circuit you had replaced in mind.

he told me the most he would run would be, 30amps...

Not all fridges run on 240. In fact alot of them dont today because they are energy star....

50 amp breaker in the room... 30 amp max he said...she said...
OP: WTF you went from too little power to over kill?
Next time [OK... Next Noob with power issues...] do it right, and Identify your loads, and check out this thread, maybe it'll help:

https://www.rollitup.org/newbie-central/607986-electric-questions-maybe-will-help.html#post8488555

Most lights, that are on [1000 watt example] should be on dedicated circuit.
Your FAU [if wired to code] will be on a separate circuit, as will your Garbage disposal, kitchen counter, and some others...

Everyone is giving advice, and most of it good...
Relax, take a deep breath, and listen to the experts.

OHM's Law... Learn it...
Your light may be a: "1000 Watter" but the ballast name plate UL rating may be over a 1000 watts...
Just saying, do a load Calc of all your items, at Name Plate...

You want your GF using a blow dryer [1500 watts] which just happens to be on your Lighting Circuit ?

Good Luck... it'll be all right...

yeah i moved my lights to a 240v 30 amp circuit just made things alot easier especially when your thinking about bringing in an electric heater which almost needs a circuit all for itself.

Smart idea it'll for sure make things alot easier. Friggin the space heater I was looking at the other day ran 1700watts. If I had to run a space heater plus the lights I'd prolly just install me a subpanel
