Type-tested switchboards are pre-manufactured electrical distribution panels that have undergone rigorous testing to ensure safety and reliability. These tests simulate actual operational conditions to verify that the switchboards can handle specific electrical loads without failure. This ensures that they comply with industry standards and provide peace of mind for users, knowing they are using a reliable system in their electrical infrastructure.
Regulated electricity tariffs are pricing structures set by regulatory authorities to control the cost of electricity for consumers. Typically, these tariffs benefit residential and small commercial consumers by allowing them to enjoy more predictable and often lower rates compared to fluctuating market prices. It helps stabilize electricity costs for these users, making budgeting easier and energy more accessible.
