Every month thousands search the Internet for “Practical Electrical”. Why?
Perhaps, most likely, they have a practical electrical problem or challenge.
It may be as simple as changing a switch in their home. Or perhaps replacing a fuse, or changing out a circuit breaker.
Maybe one of their circuits is overloading and the breaker going off.
Or maybe, they need to run a new electrical line to a washer or dryer or other appliance. Now, that is a practical electrical problem.
Often the problem is with a fan, or light fixture, or other household appliance.
How does one meet such a practical electrical challenge?
Electricians are busy. They are expensive too. Many electricians have much more important jobs to do. After all, they are involved in new construction and major remodeling jobs. And, of course, they are highly paid. As they should be.
After all, an electrician is a highly trained person. Perhaps from years in an apprentice program, or years of study at a tech school. A traditional practical electrical education is usually very expensive and time consuming.
That’s the root cause of our practical electrical challenges.
We simply can not easily or inexpensively get a knowledgeable person to help us.
Electricity is dangerous.
We all know that. Electricity kills. It only takes one mistake.
When Thomas Edison was fighting for DC electricity against the Tesla/Westinghouse AC gang, he made the point that AC high voltage electricity is very dangerous. He used the electric chair to drive home his point.
Even 120 Volts of ordinary house electricity can easily kill under the right conditions.
Before anyone should undertake ANY type of practical electrical job he or she should be completely aware of the hazards and dangers. And, how you can avoid it. Every man, woman, and child needs to know this.
Safety must always be paramount in any practical electrical activity. Even something as seemingly easy as changing a switch or fuse can be fraught with peril if improperly done. It only takes one mistake or careless action to die from an electrical shock.
Then, there are more difficult challenges in many businesses and homes. Motors, electronics equipment, anything with a high voltage source. Capacitors can hold a lethal high voltage charge for long after the equipment is turned off. Inductors can build up a lethal high voltage from a low voltage source.
So what can one do? What can you do?
The answer is to educate yourself about practical electrical situations.
“How?”, you may reasonably ask.
One way is to search YouTube for helpful videos. Sometimes this will yield a solution to a specific task. Or you might try Wikipedia. I must admit I have not been able to find much truly practical electricity information from these sources.
