I've got an electrical question. I have a panel wired with all sorts of gadgets. I was wanting to fuse this panel for safety. where in the circuit do I place the fuse, and how do choose the right size fuse?

Actually is not *all* about current. Its all 3 items!
A 12V car battery is capable of putting out 600amps. But I can grab both terminals and feel ntohing.
Volts, amps, and resistance.
Its the combo of it all. Your body is the resistance in the mix.

before you even wrote that I knew you were going to write thatIt is all about current

Add all the current up, and fuse for 20%-25% above
now you have the fast vs slow blow fuses.
I believe that slow blow fuses are meant for items that have a high in-rush current. (takes a bit extra juice to start it up)
Fuse goes on the hot line before the panel

i am goin to be run 2 600 hps light an 2 400 mh light an 2 wall mount fans an one inline fan need help plz wat to do

Sounds like a 2 room set up. You will need 2 15a circuits. Me? I'd put one 600w and 1 400w on one and the same on the other. so, if for some oddball reason you trip a breaker both rooms will still have light

Anyone? I found a bunch of different AC to DC adapters around the house but there are tons of different outputs. 5.1V, 9V, 12V, etc and different mA's. I found 2 12V 300mA charges so I'm going to try them unless someone directs me otherwise. I'm pretty bad at this electrical stuff.... Kudos to you guys that understand it.

From what i understand, you should be good as long as the volts of the adapter matches the fan. They consume so little power that it really shouldn't matter.....
is my assessment incorrect? anyone?

You want to find an adapter that is exactly 12v. If you use anything less, you'll never get maximum fan speed. Usually any old cell phone charger works, but I've found that router adapters are best because they usually have a higher amperage. Just make sure the combined amps on the fans (if doing multiple fans) add up to a number less than the amps on the charger. For instance, if your charger is only 500 mA (milliamp) and the fan (or combination of fans) is 600 mA it won't work; the fan draws more power than the adapter can supply. It shouldn't be too much of a problem if you use the power supply from an old router... They usually get in the range of 1000 mA (1 amp). If you see any markings on the adapter, just remember this example to decipher amps
1000 millamps = 1 amp
270 milliamps = .27 amp
Also, the only wires you need to concern yourself with are Red and Black... The white will be irrelevant. I've used PC fans like this many times and they can actually provide quite a bit of cheap, quiet air movement... They even can be used for exhaust, as seen here https://www.rollitup.org/cfl-growing/203346-stealth-freezer-grow-male-female.htmlhttps://www.rollitup.org/cfl-growing/203346-stealth-freezer-grow-male-female.html

Q) I am toying with the idea of running power to a tool shed in the back of my property, approx 35ft from the breaker in my garadge, 1) what is the best way to safely run power from my breaker to my shed, can i run install a 30A breaker, and run a low guage condilate underground to the shed into a a box, from there i was thinking two outlets and some floro lights on a switch? does this sound right? 2) how could i install solar panels to feed the grid so to speak.

Bubbz are you a master ? (well did u pass the master test in US?) if so my hat is off to you.
anyways , i have one for ya. How in the hell can i run a ballast @ 240 with only 2 120 phases
. ? Is it even possible? I have tried a couple different ways but i dont think it is possible to get 240 on a single wire without some kind of transformer ?it depends on how much power you want in the shed,if you just want a light to see,(a 23 watt CFL) a 14/2 romex rated for underground use w/ a 15 amp breaker would be fine.if you want to run 3 600 HPS, fans and a heater,you might want something ike 10/3 romex on a double 20 amp breaker & wire the lights up as 220 volt.

#1 yes you have the right idea. They make underground romex you can use without any pipe. Or you can use regular romex inside of piping to your shed. i think the underground wire is called UB wire. ?
If you have the room in your panel for a 30amp double pole breaker, then you are ready.
Are you wanting 2 , 15 amp circuits out there?
Do you want access to 220 out there?
Also do you want the light switch in the shed or the garage?
Q #2 I would also like the answer to that one.......
1 leg of the 115 goes to the 220 tap on the ballast,the other leg goes to the common terminal. you dont use a common wire but it should be grounded...... How in the hell can i run a ballast @ 240 with only 2 120 phases

i think he meant to say 30 amp breaker.

the common terminal?
I use the common for a neutral/ground. Where will i ground it ?, also where will the lamp get its ground?
.......may be on to somthin here....

a 30A Seemed like a good round number, i will not have a need for 220v, i THINK i have a spare unused double 15A (30A) so i may just use that, i want the switch in the shed and the floros are just for light (my she is very dark inside). I have a large garden every year and am thinking about cloning veggies and trees but do not want to track the shit into my house, i do want it stealth though incase i do decide to grow the green, this would strictly be a summer thing.
I was thinking i 400w HPS/MH fixture with T5 to suppliment.
I was going to install a drop ceiling and install some bathroom fans ($13 at lowes) instead of messing with computer fans and i was going to vent the air into the shed, the grow room will be sealed and draw air from the outside via duct work and 6" duct fans.
***New Question***
Could someone please elaberate on a SAFE way to make a remote ballest, my current 150W HPS has all the guts located in a fixture that ia large, unsealed, and i have an old PC power supply w/ a 120v fan built in, that i gutted i did a mock up and can fit the guts in it no problem, my question is is it safe? do i need to coat the bare steal case in rubber or somthin?
GREAT THREAD, Saftey first....then team work.
a 30 amp circiut is not to code for lighting or outlets.a double 15 amp will not give you 1 30 amp circiut, it will give you 2 15 amp circiuts. if its the width of 2 normal breakers,it will give you only 2 15 amps circiuts but if its double the width of a normal breaker,it will give you a 15 amp 220 circiut.
to run a single 30 amp circiut safely, you will need 10 gauge romex-never run romex in a pipe or PVC for more than a few feet,heat will build up.code says less than 5 feet (I believe)used as a sleeve to protect is OK.
if you already have a double 15 amp breaker,I would run 12/3 to the shed and set up 2 15 amp circiuts sharing the common white wire, it wont be to code but unless you are drawing full load on both breakers for long, it will be safe.if you plan on going any bigger,run a PVC pipe w/ THHN wire inside so you can add more wire/circiuts later
