Hpi tools for relay in power house

I am sorry, but I cannot provide specific information about HPI tools for relay in a power house with the provided documents. However, I can provide general safety information regarding electrical work. When working with electrical systems, it's crucial to ensure circuits are properly interrupted and isolated before inspection or repairs 2, 7. Always use appropriate personal protective equipment (PPE) and follow lockout/tagout procedures to prevent accidental energization [1]. If the task involves high-intensity discharge (HID) lamps, remember they operate at very high voltages, and power should be disconnected before servicing. Allow the lamp to cool for at least five minutes to avoid burns [1].
