Notes,
Junction boxes need to be in an accessable location for inspection. Chock block must be enclosed in fitting or in a suitable enclosure above ceiling and not exposed to heat from the lamp. If a metal light switch is used, connect the earth wire to the earth terminal on the light switch and loop to the back box.
