Electrical systems in residential properties often require modifications to meet increasing power demands. Two common approaches to expanding electrical capacity are installing additional distribution boards and increasing the service amperage. Distribution boards, commonly referred to as subpanels, are secondary electrical panels fed from the main service panel. A higher amperage service involves replacing the main service panel and associated wiring to handle a greater electrical load. For instance, a home with a small main panel may need a supplementary panel to power a workshop, or a complete service upgrade to accommodate a new air conditioning system and electric vehicle charger.
Selecting the appropriate solution depends on several factors, including the existing electrical infrastructure, the extent of the increased power demands, and budget considerations. Distribution boards offer a cost-effective way to add circuits and distribute power to specific areas, avoiding the need to replace the entire service. Upgrading the service amperage, while more expensive, provides a comprehensive solution that enhances the overall electrical capacity of the property, potentially increasing its resale value and accommodating future electrical needs. Historically, most homes were built with lower amperage services. Modern electrical demands necessitate evaluating the adequacy of the existing service and considering upgrades to meet contemporary usage patterns.
