protective device is rated not greater than 120 V, 15 A or 240 V, 16 A for the Circuit Breaker. Statement 1005

Use a multimeter to measure the resistance between various ground locations:

• Between the ground of a junction box (outlet) and the ground of a power tap

• Between the ground of a junction box and a metal water pipe

• Between the chassis and the ground of a power tap

• Between the chassis and the ground of a junction box

A good ground connection should read between 0.0 Ω and 0.5Ω.
