The only way you can connect either one or two 15 amp leads to
a 30 amp breaker is they MUST go thru a 15 amp breaker.
You can get two 15 amp leads and wire each lead thru a 15 amp
breaker and then to the 30 amp supply.
It can be in a seperate box,
with suitable 30 amp wire on the input side.
This way it can be easily removed when finished.
DO NOT UNDER ANY CIRCUMSTANCES CONNECT A 15 AMP LEAD TO A 30 AMP SUPPLY WITHOUT A 15A BREAKER.

I have three computer christmas light controllers that have 15Amp 120V Input cords comming from them. I WANT to make 2 independant 15 amp recepticals from each 30 amp breaker. Now without switching out the 30amp breaker can I just add a hot wire to one side and make it 15 amps or do I have to pull the 30 amp breaker and put in 2 15 amp breakers. The wire comming out will be rated at 15 amps. I am going to either buy a 15amp extension cord and cut the male end off or buy home electrical wire and wire a portable 4 Independent Recpticals. Which is the best way to go about this?? I had an electrician come out and he said he could do it for 150 bucks. BUUUT It just seems so simple. I know the basics I just need to know if I can leave the 30 amp breaker on there and use one side for one receptical and the other side for another receptical. Is that safe? In not I will pull the breaker and put two 15 amp breakers in. But I am only a renter and I do NOT want to change anything. I want it TEMPORARY you know wire it up for christmas and pull the wires like it was never there. Now the A/C will not be used at all. AND the dryer will only be used while the lights are off.
