    What this does and doesn't tell you

    • Motor ratings are usually shaft output. The power drawn from the supply is higher.
    • Motors draw a big surge when they start.
    • 240V AC mains can kill. In Australia, work on household mains wiring must be carried out by a licensed electrician. Low-voltage DC systems can still deliver very high current.
