    Too many outlets on one breaker
    Basically I have a hobby room with 5 outlets in it and I just found out that they are all wired to one 20 amp breaker. My question is... Can't I just take the cover off the breaker box and put two more breakers in two of the empty spaces and pull the wires off the existing breaker with 5 on it? In other words, are there five separate sets of wires from all five of those outlets going to that one breaker, or are they tied together somewhere before they hit the breaker box.
    I just want to be able to have more juice able to come from those outlets without me throwing a breaker every two minutes.
    Please let me know if it is as simple as taking the cover off the box and re-routing a few wires to new breakers, or if those lines are somehow somewhere tied together.

    Huh? Five outlets on a 20 amp line should not in and of itself be a problem.

    A 20 amp circuit can deliver 2400 Watts of power to the circuit. As long as you don't plug in more than 20 amps you should be fine.

    Also, rewiring the panel is not a trivial task. If you do not know what you are doing you could get very dead, very fast.

    The receptacle outlets are wired in a Daisy Chain arrangement. The Power line (Normally Black but it could be yellow, blue or Red depending on the cable that is being used) would be attached to the breaker. Neutral (gray or white) would be tied to the Neutral Bus Bar and the bare copper ground wire would be tied to the Grounding Bus Bar. You should only find one Cable containing the Black Neutral and Bare ground per breaker. If there are more then on, then it is a violation of the NEC Code.

    The wires are not all "tied together" somewhere. They most likely go from one box to the next and so on.

    You would be better off having someone run a new circuit to the one or two items that draw the most power.

    Like Don said, 5 receptacles on a 20A circuit is not much at all.

    Thanks Don,
    And your right under most circumstances I'd be O.K with those 5 on that 20 but it's a dark room for photography and my enlarger is 1500 watts itself and then I'd like to run a photo rinse trey that has a series of pumps not to mention a series of other things like a computer that will have quite the draw with a series of three different printers, from small to very large... So if I'd like an overkill and have a 20 amp service running two outlets twice and one outlet alone on its own 20, for a total of 3 20's holding all 5, and actually now that I looked there are 6 so I thought 2 on each of the three 20's... If I want that, what's my best bet, have someone professional come in? Or is it something I can do myself if I'm handy and somewhat knowledgeable?

    Seems to me you left some critical information out of your initial post. That's not fair. :-)

    Here's some more for you to consider. Do you have any equipment that must remain on constantly for more than three hours a day? If so, then you must multiply the amperage by 1.25 to allow for the increased load.

    Also, you need to figure out what the total load for the equipment is needed and which devices need to be on a dedicated circuit and which can share a circuit.

    Best method would be to list each piece of equipment and the amperage needed for each. Factor in any continuous loads at (Amperage X 1.25). Generate your load total, then divide by 20 to get the minimum number of circuits needed.

    In your situation, I would get several estimates from "Licensed" electricians and pick the best price.

    Thanks again Don,
    Hey one last question, I own an apartment building and I have 18 units about two commercial units, Each one of the residential units is on a 15 amp breaker (I know, its old) During most of the year it's OK but when everyone runs their A/C units the breakers start a throwing. Is it possible to pop each of those 15amp breakers out and replace them with 20 or 30, or do you have to run new wire to each apartment. In other words, is fixing the problem as easy as putting in new breaker switches or is it way more involved...
    Thanks for your time

    What is the amperage needed for the A/Cs? Are they window units?

    Something you absolutely cannot do:

    Use an OCPD (breaker) larger than the wire it is protecting. For example, using a 20 amp breaker on a 14 AWG wire. Not only is this a code violation here in the U.S.A., but it is a very nasty fire hazard.

    If you have a 14 AWG cable for the circuit, then you are limited to a 15 AMP breaker. If you want a 20 amp circuit, you must use 12 AWG. For 30 amp, you need #10 AWG. And so on. See NEC Code 310.16

    Because of the building contain, I strongly suggest that you contact several electrical contractors an get bids on bring the property up to code. It really is in your best interest to get the work done.
