What do the numbers on a circuit breaker mean?
Those circuit breaker numbers mean the amp rating of a particular circuit breaker. These include its kiloampere rating, like 5KA or 10KA, which indicates the maximum amps it can trip. You may also see 110 VAC, 220 VAC, or 240 VAC printed on the unit, which simply means its voltage rating.
What are the symbols of an electrical circuit?
Electrical Symbols
- Ground or Earth. A ground symbol (IEC symbol 5017) identifies a ground terminal.
- Resistor. A resistor reduces current flow.
- Switch. Disconnects the current when open.
- Capacitor. A capacitor symbol shows two terminals running into plates.
- Fuse.
- Antenna.
- Inductor.
- Transformer.

How do I know what breaker I need?
Circuit breakers have markings stamped on the side of them and are usually located inside the panel cover door. There is a label that will tell you what type of breaker is needed for installation in that particular panel.
How do I know what type of circuit breaker to buy?
How can I tell what AMP my breaker is?
A panel’s total amperage is printed near or on the main circuit breaker, which controls all the circuits in the panel. Most breaker boxes are 100, 150, or 200 amps. Add the amperages of all the individual breakers in the box. The total might be more than twice the total amperage of the box.
What are the basic symbols of Electrical Engineering?
Part 1: Basic Electrical Symbols. Basic electrical symbols contain earth electrode, cell, battery, resistor, etc. Whether you are a novice or a professional engineer, these basic symbols can help create accurate electrical and circuit diagrams in minutes. You can depict a complex electrical circuit with the standard and simplified electrical
What are the basic electrical symbols in a schematic diagram?
Some most commonly-used basic electrical symbols in schematic diagrams are shown below: Example one: There are three D-cells placed in a battery pack to power a circuit containing three light bulbs. The resistor symbol represents each light bulb. The connecting lines are used to connect the symbols.
What are the advantages of using standard electrical symbols?
Electrical symbols are standardized throughout the industry, so it is easy to achieve the ability to interpret the meaning of the symbols. With the standard electrical symbols in Edraw, you can create a circuit diagram that shows the actual layout of the components simply and quickly.
What does the connected wire symbol look like on a switch?
The connected wire symbol looks like two parallel lines emerging from a two-point while one gets extended. Connected wire represents the connection between two conductors. A Single Pole Single Throw switch is an ON/ OFF switch with the poles to stand for the number of poles to connect.
