Repairing blown automotive fuses requires substantial knowledge about its placement and how it works.

Automobile fuses come in a type of glass formation. It is cylindrical in shape while the ends are stainless steel and made of glass at the center. Others are made of plastic. It also has links acting as a backup fuse.

Below are some types of automotive fuses:

• Mini (for small-current app (more…)

An Automatic Transfer Switch is an automatic transfer of power source from one to another, this type of switches is more convenient compare to the manual type. An electrical transfer switch is very useful nowadays, because when the main power source is disconnected, it will automatically transfer the power to another electric system.

Electrical transfer switches can be use also when there are changes in voltage power supply. If the volt (more…)

A really good and much under rated feature of the Danfoss BD35 and BD50 compressors are their inbuilt diagnostics function. Before doing anything else with a 12v or 24v fridge that is not working is make sure you test the controller on the Danfoss BD35 or BD50 compressor.  The following testing procedure must be carried out.

1.     Turn off the breaker (or remove the fuse) supplying DC power to the system.

2.     Use a s (more…)

The paper deals with the directions of the state-of-the-art changes in the field of residual current circuit breakers, with particular emphasis on standards changes due to new requirements of environment, reliability of operation, operation at high frequencies, and use of voltage-dependent switches.

Protection switches, or residual current devices are in practice a widely used way of protection against indirect contact (more…)

Every air conditioning system has a different way of getting electricity. Central air systems need different wiring than window units. There are window units that operate on 110, 120 and 220 lines. The central air conditioning systems usually operate on 220 lines. Depending on where you place the air conditioning unit, you might need to install some wiring and a receptacle to operate the unit. It is important to know what type of unit you are (more…)
