Additionally, older wiring can present safety hazards that can be corrected only by a wiring upgrade. Homes built before 1960 typically feature wiring wrapped in rubberized fabric that provides little insulation when the material becomes brittle and frayed. Substandard insulation can be a problem in crawlspaces and attics. Homes built in the 1960s and 1970s frequently were built using aluminum wiring. Aluminum wiring can loosen over time, causing electrical shorts and overheating that can lead to fires.
Upgrading your electrical system will provide the infrastructure for a more satisfying lifestyle and insure a safe environment. It is therefore critical to consult an expert before upgrading your appliances and other electrical devices. Emsley pointed out that the technicians at Bel-Red Electric have the professional training, expertise and experience to evaluate a home's electrical panel and wiring as a critical step before upgrading electrical appliances.
