San Antonio has many old neighborhoods that have aging wiring systems that were not intended for contemporary electrical requirements. Present-day systems that use air conditioning, and other electronic and electrical appliances, can overburden the existing wiring and circuits.
The U.S. Energy Information Administration (2023) notes that over 87% of U.S. homes use electrical systems to provide cooling, which in turn increases the house’s electrical panel system. This is more impactful in the hot Texas climate.
According to NFPA (2023), electrical failures and malfunctions are one of the leading causes of fires in homes throughout the United States.

Most residential work is done with copper wiring. This is due to the fact that copper is both more conductive and more durable. Aluminum wiring is common in older households, but can be unsafe and may require an electrical upgrade. Circuit breakers are designed for specific systems and are further categorized by their load capacity.
OSHA electrical safety guidelines signal that effective grounding and insulating diminish the risks of shocks from installation and maintenance work (OSHA, 2023).

Electrical Installation and Repair Process
The first step in the process is an inspection. Here an assessment of all panels, the quality of the wiring, and the load is performed.
The contractor will next perform a load calculation to determine the necessity of an upgrade. Once this load calculation is completed, the contractor will obtain the necessary permits from the City of San Antonio Development Services Department.
The installation may include rewiring, breaker replacements, or any other type of grounding systems. The final step in the process is a test of the installation to assure voltage and balancing as well as compliance to standards.
In the City of San Antonio, building codes state that all electrical work must be inspected prior to any other work to the building that may close any walls or that would allow any of the systems to be activated.
