Most electrical tasks should be left in the hands of licensed electricians . However, if you think you may need electrical repair near Dublin, then you might benefit from understanding more about how your home electrical wiring works. Watch this video for an introduction to one type of electrical system component called transformers.
Transformers can be seen on the ground or at the top of utility poles, and their function is to increase or decrease electrical voltage before sending electricity on to its destination. This step is important because not all voltage levels are safe for residential or commercial use.
Transformers first transform voltage to safer and more manageable levels at substations, and then again further along in the distribution system before feeding it into the wiring to your electrical outlets and appliances.
