Good point. I should have added to verify the existing wire size. Per code however it is 15 amp to 14 ga, 20a to 12ga and 30a to 10ga.

So I have a question that I have been trying to look for a answer for. I have a 12v .70 A 200mm computer fan that I am wanting to use as a intake for a 3x3 tent on the way. Problem is I only have a 12v .75A power adapter to splice and connect it to the fan. I was reading around and it looks like it would not cause any issues other than maybe running the fan a little quicker. Is my thinking correct in this?

There's a couple different ways you could set it up. I always run heavier than i need because why not? Think future.If you have 200amp service, i would come off your main with 8g to a 100amp sub. From your sub you can run 12g to each separate 600 watt light. So each light will have it's own breaker, 4 breakers in your sub. And since you went heavy to your sub, you have more options for future add ons. Just make sure the leg you come off in your main isn't loaded. Dryer, stove etc.. Like i said there's a couple different ways depending on your service and type of panel and how your existing is set up. This is one way that is safe.

google "wire ampacity chart." almost all building wire these days is THHN 90 degree. http://www.armstrongssupply.com/wire_chart.htm
12 gauge is rated for 30 amps.

Guess I have a ballast/bulb question. My ballast says to relamp with M138/E bulb. I bought a M153/E bulb (never looked at box till I got home) the bulb I bought,also states on the box " use only with ANSI M153/E ballast. I'm not sure what type of ballast I have. I bought it new 1 year ago. It was a wall pack outdoor unit. I converted it to a remote ballast unit, so I could run the bulb in an air cooled hood.But threw the paper work away and now have no idea if its an ANSI M153/E ballast or not. Any ideas on what to do?

Hiya M8,
ANSI 138/E and 153/E are both Pulse Start MH Ballasts/Bulbs of the same family. They can be used in the same ballast as long as they are the proper rated wattage of course. So you are good to go.
Peace

Thank you. Glad to hear it. Yes it is the same wattage.

you could also run a heavier wire like 10/3 split of two 15amp breakers whiich you use the black and red as 2 different circuit 15amp each or if you really want use also the white (nutural) as another circuit---- im running 4 600watt hps 2 8inch 750 cfm fans co2 controller enviro controller 2 16inch wall fans and a quantum t-5 badboy with 16 bulbs all my equip. is 240v which cuts your usage down in half and i have no problems.....not allways a great idea to use the nutural unless you really need a 3rd circuit

So I went o Home Depot and they had 2 2' t5 fixtures for $20 so I picked 2 of them up for my veg tent that has 6 seedlings about 4" tall. Anyways, they were just the fixture and bulbs with wire to be wired to romex or whatever inside a ceiling. So I grabbed the male ended cord with the white green and black wires on the other end and connected them to the green black and white wire on the fixture so i could plug it into a regular outlet. When i plugged it in (I read somewhere online i could just plug them in like that) they lit up for about 5 sec and then my breaker popped. It stays popped now, when i go to my breaker box to flip the switch it wont stay on. Im a plumber not an electrician so any advice??

so i need to run a nit of an extension cord that really isnt going to be moved once ran. also its going to be out of the way of foot traffic hung in the rafters. i guess my question is will a 50 ft run of type NM-B 10/2 be enough to supply 30 amps and 4000 watts to my new location from a 30 amp dryer outlet with the correct ends since the ground in the cable is not insulated but the others are? or should i go with some 10/3 sjo instead? problem lies in it being twice the cost. can i make it work or should i spend the cash for the good stuff so i dont burn my casa down? lol.
hi i have a 6oow compact magnetic ballast with a philips 600w hps bulb when its been on for about 6 hours it starts to make a loud buzzing noise for about 10 seconds then stops for a minute and starts again. and i think it stops after about 1 hour i think i have heard it before when i plugged a extra fan into the ring main (circuit) it buzzed the same for about ten seconds but i checked the amps and i have plenty to spare i checked all the connections from ballast to bulb and they are all fine. any help

Magnetic ballasts are inherently "dirty" power users. They actually have a warmup and a cool down cycle during normal operation. How old is the ballast and you really should have it on its own circuit if possible.

Sounds like your capacitor is going.
