circuit supplying the existing transformer or ballast will be within the voltage ratings of the new LED power supply, and have a current rating not
exceeding 20A, or that permitted by applicable local, state, or country electrical codes (whichever is less).
If removal of the existing lighting equipment (see Step 2) eliminates the disconnect switch, as required by applicable local, state, or country
electrical codes; a new disconnect switch must be installed.
If required, the disconnect switch shall be installed by qualified personnel, in accordance with applicable local, state, and country electrical codes.
Repair and seal any unused openings in the electrical enclosure. Openings greater than 12.7-mm (1/2-in) diameter require a metal patch
