The circuit breaker or electrical panel is an essential device in the modern world, and one of the most important safety mechanisms in your home which is why it is important to be maintained by a Residential Electrical Service Electrician. Whenever electrical wiring in a building has too much current flowing through it, these simple machines cut the power until an electrician can fix the problem. Without circuit breakers (or the alternative, fuses), household electricity would be impractical because of the potential for fires electrocution and other problems resulting from simple wiring problems and equipment failures. To understand circuit breakers, it helps to know how household electricity works. |
Electricity is defined by three major attributes:
Voltage: is the "pressure" that makes an electric charge move. The conductor offers a certain amount of resistance to this flow, which varies depending on the conductor's composition and size.
Current: is the charge's "flow" meaning the rate at which the charge moves through the conductor.
Resistance: the conductor offers a certain amount of resistance to this flow, which varies depending on the conductor's composition and size.
Voltage, current and resistance are all interrelated: If you increase the pressure working on electric charge or decrease the resistance, more charge will flow. If you decrease pressure or increase resistance, less charge will flow.
The power distribution grid delivers electricity from a power plant to your house. Inside your house, the electric charge moves in a large circuit which is installed during construction by a Residential Electrical Service Electrician. One end of the circuit, the hot wire, leads to the power plant. The other end, called the neutral wire, leads to ground. Because the hot wire connects to a high energy source, and the neutral wire connects to an electrically neutral source (the earth), there is a voltage across the circuit.
The power distribution grid delivers electricity at a consistent voltage but resistance varies in each house, Electrical Services in Calgary will know how much resistance your house has and what is needed according to your appliances. All of the different light bulbs and electrical appliances offer a certain amount of resistance, also described as the load. This resistance is what makes the appliance work.
In building wiring, the hot wire and the neutral wire never touch directly. The charge running through the circuit always passes through an appliance, which acts as a resistor. In this way, the electrical resistances in appliances limits how much charge can flow through a circuit This keeps the electrical system running smoothly most of the time. But occasionally, something will connect the hot wire directly to the neutral wire or something else leading to ground in this case an electrician is needed to fix the problem.
The electrical panel’s job is to cut off the circuit whenever the current jumps above a safe level. This is why it is vital that your electrical panel is in the best condition possible and can handle the amount of voltage needed. Electrical services in Calgary upgrades panels in order to keep everything running smoothly and safely.
