Answer for USA, Canada and countries running a 60 Hz supply service.
Yes. The NEC requires that your service disconnecting means be as close as practical to where the service conductors enter a building. In a home, your service disconnecting means is the main breaker in the panel.
If you choose to move your panel away from the closest practical location, you must install a separate disconnecting means and make your grounding conductor, grounded conductor (neutral), and grounding electrode conductor (conductor to your ground rods) bonds within that enclosure. You must then isolate your grounding conductor and grounded conductor (neutral) everywhere else. This is where the confusion arises because in homes we are used to sharing the same set of terminals for the ground wires and neutrals.
In this type of installation you must have a ground bar which is bonded to (usually just connected to) the panel enclosure for your ground wires and a separate set of terminals for your neutrals that is isolated (insulated) from the panel enclosure.
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

If it's an electric oven, the fuse may have blown, or the circuit breaker may have tripped. Do you know where your household fusebox/ breaker box is?
Need to know what the wattage or the amperage is of the appliance. The load amperage is what governs the wire size and the breaker to protect the circuit.
The wire is sized to the breaker in the main box that is feeding the subpanel. The calculations for the subpanel is based on what devices will use the subpanel and an estimate of duty factors for the devices. An electrician can provide this information, or you can look on-line in the National Electric Code for estimation methods.
In the breaker box
Yes there is one breaker that can shut the whole house off. it's usually at the top of the box
in the fuse box ,on the drivers side of the dash.it is a 30 amp circuit breaker.
could be bad circuit breaker
An electric circuit breaker is switch that is used to protect electrical circuit from a short circuit or overload.
The amperage capacity of the main bus bars and the connection of the main breaker to the bus bars.
mineature cicuit breaker
try higher amp breaker
No. A relay is an electric switch and a circuit breaker is an overcurrent device.
It is the 30amp circut breaker on the right side of the fuse box under the steering column
Breaker boxes do not have fuses associated with them unless the main disconnect is independent from the breaker box. If that is the case both fuses have to be the same in the main disconnect that protects the breaker box.
no, a fuse box has fuses
a box where you break circuits...

On new installations, load calculations are based on square footage of the building. The second calculation is based on the type of equipment that is to be connected. If you want to measure the load on an existing breaker box, find the current draw coming into the box times the highest voltage coming into the breaker box and multiply them together for the total wattage of the breaker box at that moment in time.
Yes, but the 60A breaker will trip when your house box reaches 60A draw. I would not recommend it.
first run electric cable to garage,10-3 with ground is best,you will have to put at least a 30 amp box in garage more if running 220. if just lights and power tools on 110 then you will be fine!! in box connect red wire to proper lug in box and black wire to proper lug. run 14-2 to lghts!! you can use 12-2 also it is a heavier cable!! at house breaker box run the 10-3 cable to its own breaker in box,at least a 20amp breaker!! red and black wires go to breaker and white goes to neutral bar connect ground to ground bar or neutral bar also!! use a double pole breaker in main box.
I doubt if the 125 amp breaker will fit into a 100 amp box. This is due to the rating of the box only being rated at 100 amps. If this exchange could be made then the service conductors feeding the box must be upgraded to take the 125 amperage that the breaker will allow on the conductor.
Usually a double pole 30 amp breaker for and electric dryer.
Don't mess with an electric panel if you are not absolutely sure what you are doing. To add a circuit you need a breaker, wire sized to the new breaker and the outlets, lights or devices that are powered by the new circuit. If you have spare slots in the panel you need to get the proper breaker for the panel and just knock out the panel cover for the new breaker. If there is no space in the panel, you may be able to find a dual breaker that just takes up one space in the panel and substitute for an existing breaker.
