Heavy Ups and Fuse Panel Replacement

The Maryland, Virginia and Washington, DC area is home to many very old neighborhoods. While often charming, older homes tend to not always have the most up-to-date electrical systems – many have substandard wiring or undersized systems. These days, things like central air, modern appliances, computers, HDTVs, etc. can overload older electrical systems. This can cause frequent circuit breaker tripping, increased risk of electric shock or a full on electrical fire! If your home’s electrical system can’t meet your electrical service needs, call the expert electricians at Kolb Electric!

Electrical Heavy Ups

Upgrading your home’s electrical service is known as a “heavy up” – basically it involves removing your old electrical panel and replacing it with a larger, safer one. Heavy ups always require a permit, which means you’ll have to call one of the trained, fully trained electricians at Kolb Electric. After the heavy up is performed, the county inspector and a representative from your utility company will have to come out and inspect the job. A heavy up will give you more stable power, better grounding, 200 amp service and plenty of room for additional circuits – and, most importantly, no more dangerous, degenerated parts to worry about!

Fuse Panel Replacement

Before we talk about fuse panel replacement, it helps to talk about what an electrical fuse panel actually is. Prior to 1950, most homes used 30-amp fuse panels. These fuse panels used two-plug fuses to protect branch circuits and a knife-blade switch to disconnect the power. Fuses were installed in a ceramic fuse holder mounted inside a black metal enclosure.

Between 1950 and 1965, 60-amp fuse panels that featured a 240-volt feed were introduced. The 60-amp fuse panels featured two cartridge fuse blocks and four-plug fuse blocks. The first cartridge fuse block held the 60-amp fuses and was used as the main disconnect. The second was used as the appliance feed and held 30-amp fuses, feeding power to things like electric dryers, water heaters, ovens, electric ranges, etc.

The circuit breaker was first introduced in the 1960s, providing expandable circuit spaces, 240-volt, 100- and 200-amp service. These days, 100-amp breakers are the minimum allowed for your home to be up to code. If your home still has an old fuse panel and you want to upgrade to a 100- or 200-amp circuit breaker, call the expert electricians at Kolb Electric!
