Here's a quick review of how to use a fuse box (with the screw-in fuses) safely and some discussion about what to look out for in an old house.
Here's how to understand the difference between screw-in fuses, bases, power rating, and what they're used for. Fuses for standard circuits (not high-voltage appliance circuits) are called plug fuses and have screw-in bases.
Fuses for residential use will use two types: screw-in or cartridge. A small and round screw-in fuse has a glass body that protects the fusing element (a thin metal strip) and a conductive metal base that screws into the fuse box, much like a light bulb. You know, the ones that either look like a small glass eye with a screw-in base or one of your grandfather’s shotgun shells? We have come a long way since those were the electrical panel box of choice. So, let’s look at these older fuse boxes and explore the idea of changing that fuse box to a breaker box. Old electric panels with round, glass screw-in type fuses use a simple, dependable technology to avoid that problem: a small metal strip, visible through the window in the center of the fuse, is calibrated to overheat and melt apart when amperage (current flow) exceeds the rating on the front of the fuse. Types of Fuse Boxes. If you decide not to upgrade your electrical system, thus upgrading to an electrical panel, you’ll need to know the different fuses. In essence, the fuses dictate which fuse box you need when you replace it. Edison Panel. An Edison panel uses Edison fuses that screws in like a light bulb — hence, its name.
But the National Electrical Code (NEC) has safety standards for old screw-in type (Edison) fuse panels that are still in use. Their requirements are for shock protection when changing fuses, and to eliminate the possibility of installing a fuse with a higher amperage rating than the wiring will safely conduct. The supply should connect to the center contact of the screw-in fuses, the output to the outer shell. I would not around with changing to screw-in breakers. I'd replace these historical artifacts with modern breaker panels ASAP. To turn the power off to an electrical circuit, flip the breaker switch toward the outside of the panel or unscrew the fuse. To turn the power to a circuit back on, push the circuit breaker switch toward the center of the box or screw the fuse back in. The fuse box, the precursor to the modern circuit breaker panel, performs the same role as the control center for all the electrical circuits in the home. It features lugs for connecting the service wires that carry alternating current (AC) from the service provider.
