Life is full of warning signs, but we don’t always pick up on them. A circuit that constantly burns out its fuse does not need a larger-amperage fuse. Instead, reduce some of the loads and their demand for current. Remember, electrical systems are very logical and safe when used intelligently. If you push them beyond their limits, all bets are off as to how well they’ll behave.
An orderly electrical system doesn’t overheat, start fires, or inordinately dim your lights. These are all signs that you have problems. (A fire means you’re too late.) If you have an older system that still uses fuses and does not have a grounding conductor, you need to be more observant of your usage and how your system reacts. Electrical problems sometimes require detective work. When an appliance doesn’t work at one receptacle, try it in another before you start tearing it apart. It might just be a bad receptacle or a loose terminal screw.
Remember that older, fuse-based systems weren’t designed for all the electrical loads we surround ourselves with today. These systems are safe when used judiciously.
