I'm re-finishing part of my basement, theres only a single outlet in what is now a bedroom, and I'd like to put in a bunch more as well as run electrical to the adjoining room that I'm finishing. The problem is that those two rooms are going to have a lot of equipment in them and so are going to need to be able to support a fair amount of power. since right now theres only one outlet its obviously only one channel (i dunno if thats the proper term) on the fusebox, and I think if i ran everything off that one it would trip a lot. Can I install a second fusebox in the new room running off that single channel? or do i need to run other 'channels' off the existing fusebox into the two rooms.
I'm not an electrician but I do know some. First, by channel I believe you're refering to the
breaker. The breakers are rated by AMPS, usually (for residence) they're 15 or 20 amps (give or take). Your washer and dryer, along with any other major equipment are probably running on larger rated breakers.
Simply adding another fusebox/breaker panel in the basement from the existing power source will not be any better than splitting the lines and just running them to other receptacles. If the power is insufficient you would have to install a new breaker inside the main box and run all new lines to the basement.
Aside from that single receptacle in your basement you need to find out what else is running off that breaker. IF that receptacle (and probably the basement light) is the only thing, you might be in luck. But there is a chance that other outlets/lights on the main floor are running off the same one, in which case, adding two more rooms of electrical will in all likelihood overload and pop the breaker. To find out you'll have to turn off the breaker and test the electrical in all surrounding areas.
Keep in mind that while each breaker supplies power to a number of outlets, and overloading the breaker will cause it to pop, you also have a MAIN breaker (it's reffered to as the MAIN) which can also pop if the accumulated power from ALL the breakers is overloaded. This would be the product of adding a new breaker and running new lines when the MAIN was not equipt for that. If this is the case, you will be screwed. Because I believe the next step up from the MAIN is the transformer which is run and operated by the city, and you will not be able to mess with that. The chances of this happening, although low, might depend on when your house was built. As you can imagine, older houses are not as likely to be set for this.
What I've told you are not necesarily facts, rather what I believe to be the case. I could be wrong so dont take my word for it. My intent with providing you this information is to give you a greater starting point and help you to know what to look for and which questions to ask.
Last thing I will say here is this: It is in your best interest to consult an electrician and maybe even have him do the work for you. You dont want to fuck around with electrical if you dont know what you're doing. You can do damage to yourself and/or your home if you dont do everything properly. If you don't at the very least have a multimeter I can already tell you to STOP and call an electrician.
Hope this helps.
