A:

Quick Answer

One common issue in wiring a fuse box in a home is that the unit no longer meets minimum electrical codes. Other issues include the limited number of circuits and overfusing. A modern circuit breaker panel overcomes these problems.

Both fuses and circuit breakers provide protection from overloaded circuits and shorts. They interrupt the flow of electricity to the circuit to prevent overheating and electrical fires. While fuses and fuse boxes were state of the art many decades ago, they are obsolete as of 2015. While older homes with these systems are allowable due to grandfather clauses, most lenders require the replacement of such units when the home sells. Insurance companies also sometimes require replacement before covering a home.

When fuse boxes were common, in the early 1900s, a circuit for an electric range and four branch circuits were sufficient for the home's electrical needs; however, modern residents use much more power, and four branch circuits are no longer sufficient. The circuit breaker setup offers many options not available through a fuse box.

Overfusing is the practice of putting in a larger fuse to prevent a blown circuit. The larger fuse allows more power to pass through without burning through the fusible link. However, the wiring is incapable of carrying the additional load without damage. This practice leads increases the temperature of the wiring, causes melted insulation and sometimes causes electrical fires.
