How do you wire a 15 amp 120V breaker in a 240v 30 amp breaker panel?
Look to see if the 30 amp panel is fed with a two wire or a three wire. If it is a two wire then you are out of luck. If the panel is fed with a three wire then the panel should have the neutral terminated in the panel. It is this neutral that you need for 120 volt connections. You didn't state how many panel slots there are in the panel. If you are able install a 15 amp breaker into the panel and connect the wires going to the load. The black wire will go to the breaker and the white wire will go to the neutral bar in the panel.
Is it safe to have two black wires two white wires and two ground wires on a single breaker?
Hopefully just the black wires are on the breaker. Two circuits on one breaker. Shouldn't be a problem. It would depend on how many outlets or lights were on the breaker in total. Even then, there is very little chance of something drawing current from every outlet at the same time. The only thing is you can't put two wires under one breaker (by code). You would have to wire nut them with a pig-tail then just put the one wire under the breaker.
Where could I find your main circuit breaker and a siemen panel?
The main circuit breaker is typically mounted to the meter base, and is usually outside, where the electrical service comes into the house. Siemens is a large manufacturer of electrical components. You should be able to find Siemens equipment at several electrical supply wholesalers in your area. Note that many of the electrical wholesalers will NOT sell to the public; you may need to find an electrician or other contractor to purchase Siemens equipment.
Where do you connect the ground cable in a panel with no ground bus?
Many panels do not have a ground buss. Look for a set of screws mounted directly on the back of the panel adjacent to the breaker outputs. These are to be used for the ground wires. Square D panels are one of many that use this configuration.
How many wires are used for a 460 volt circuit breaker?
If the load is single phase and the load requires 460 volts to operate, then two conductors will be needed and they will connect to a two pole breaker. If the load is three phase and the load requires 460 volts to operate, then three conductors will be needed and they will connected to a three pole breaker. The sizing of the wires will depend upon the current that is drawn by the loads.

Is it OK to have 250 A of breakers in a 100 A panel?
Yes. Many installations have breaker totals higher that the main breaker of the panel. It is worked on a percentage basis. Not all of the breakers will be on at the same time. In a home, on a 100 amp panel the average load is 50 - 60 amps. The 100 amp main breaker is protecting the 100 amp rated panel board. If the load current goes higher that the panel board is rated at, the main breaker will trip to protect the board.

How many wires can be connected on to a 20 amp breaker in NH?
Code only allows one wire to be connected to a single pole breaker. Any additional circuitry has to be done in a junction box downstream from the breaker.

Function of panel meter?
What is a Panel Meter? A panel meter is an instrument that displays an input signal in either a digital or analog form. Many panel meters also include alarm options as well as the ability to connect and transfer data to a computer. OMEGA's iSeries panel meters are available with an ethernet option which allows the panel meter reading to be accessed across a local area network (LAN) or even through the internet. directly quoted from here: http://www.omega.com/PanelMeters.html
When testing for current in a cable with 11 color-coded wires the author used a meter to test twotwo wires at a time. How many different tests are required for every possible pairing of twot?
when testing for current in a cable with eleven colored-coded wires, the author used a meter to test five wires at a time. how many different tests are required for every possible pairing of five wires?

Where is main breaker switch?
a circuit breaker trips on overload,if this breaker has tripped many times it may be worn out,if there is a overload happening the breaker is doing it s job keeping you safe.Main breaker needs to be replaced when your meter has been pulled(removed from metersocket)Have a electrician look at it and verify problem, you should not attempt to change out yourself it will be live.......
Can multiple circuits be connected on one breaker?
Multiple wires can be connected to one breaker but the one breaker IS a circuit. As long as the load is not more than 80% of the breaker capacity (example: a 20 amp breaker can only have 16 amps or 1920 watts at 120 volts) then by code as long as the load is not a specialty outlet of some sort, you can have as many outlets you want.
I am adding a 30 amp sub panel - the problem I have is the neutral bus is full what are my options?
Best answer - If panel can accept, add an additional bus on the other side and bond the two together. Least desirable answer - split bolt the neutral to one of the existing. Under no circumstances should you place multiple wires under one terminal. <<>> The neutral wire for the sub panel will only be a #10 conductor. Neutral wires can be doubled up under a single screw in the neutral bus. Turn the main breaker off to do this installation. Double up two #14 neutrals to make room for the #10 neutral wire. There is no code rule as to how many wires can be installed under a terminal on the neutral bus. There is a code rule though about not doubling up circuit feeders under one breaker terminal.
