These are basic electrical images taken from the field. Electrical alterations are frequently performed by non-professionals or amateurs. Because of the inherent risks associated with electrical work, you should only undertake electrical work if you’re qualified to do so. If you’re not, you should retain a qualified licensed electrician.
I have provided captions at the bottom of each picture. If you click on an image, it will enlarge and you can use the arrows at the bottom of the image (right or left sides) to scroll through the slideshow.
