depends on what you want to test it for. best way is with a multimeter. Radioshack or an electronics parts store will have them I'm replacing a ceiling light fixture attached to 2 3-way switches. Original question clarified: After replacing the switches with the breaker off, I turned it on and checked the wires in the ceiling box. Using a Radioshack Micronta Range Doubler on the AC side, The switches seemed to function normally with each switch capable to turn on and off the circuit from either side. However when both switches are turned off, their is a small current detected in the wires in the box.
The other wiring I have discovered is that the common wiring in the 2nd 3-way switch is also connected to the common wiring of an adjacent unipolar switch (on another circuit and light) in the same box.
You need to understand the symbology used and the standards associated with such drawings. Most professional drawings have various notes and legends that tell you about the symbols and various important parts of the drawings. You have to understand how electricity works and what the drawing represents. For example in drawings for commercial spaces there may be different drawings for different purposes, such as a reflected ceiling lighting plan.

The single line diagram is circuit diagram where "one-line" is shown to represent three phases of a three phase power system. In addition to showing the ratings and size of electrical equipment and circuit conductors, a properly drawn one-line diagram will also show an electrically correct distribution of power with respect to current flow from the power source to the downstream loads or panelboards.
the circle diagram of induction motor is used to find the losses and efficiency of induction motor
single line comment are comment written in single line.in c there are two types of comment single line and multiple line.single line comment is written using // and multiple line comment is written between /*comment*/.compiler does not compile comments.it is used for better understanding of program.
'single line diagram' or ' one line diagram' is basically a first step in planning substation layout providing the information about switching and protection arrangement required including the incoming lines and outgoing feeders. 400kv, operating voltage, which is to be considered for the ratings of electrical equipments

There is no difference...same thing
The SLD stands for Single Line Diagram. There can be many other acronyms of SLD, but Single Line Diagram is the best. Single Line Drawing can also be another one.
Single sine diagram is graphical representation of electrical circuit drawn using single line instead of drawing 3 separate lines for three phases.
The single line diagram is circuit diagram where "one-line" is shown to represent three phases of a three phase power system. In addition to showing the ratings and size of electrical equipment and circuit conductors, a properly drawn one-line diagram will also show an electrically correct distribution of power with respect to current flow from the power source to the downstream loads or panelboards.

polyline is a 3d line where line is a 2d figure if a diagram has been drawn with polyline and line, if we click on the diagram made with polyline whole diagram will be selected where line didn't make it
