Step 7 - Connect load conductors
Follow the instructions here for each dimmer type you are installing.
15/20 AMP INCANDESCENT & LOW-VOLTAGE LOADS:
- Referring to Figure 6, connect the load conductor for the first (upper) dimmer to the upper load terminal, and the second load conductor to the lower load terminal.
Terminate their respective neutral conductors to the adjacent neutral terminals located directly behind the load lug.
Tighten all lugs according to Table II.

LOW-VOLTAGE APPLICATION NOTES:
When using TOPAZ 12 dimmer modules with transformer loads, the kW rating becomes the kVA rating. VA ratings are found by multiplying the input voltage (12OV)
by the current flowing in the transformer primary (120V side) for all transformers connected to the dimmer module. When calculating VA load keep in mind that
transformer losses add many VA to the published VA load rating of the transformer. When current cannot be measured, derate the kW rating of the dimmer module
by 25% and add up the kW ratings of the lamps involved.
Caution:
Operation of a dimmed transformer-loaded circuit with all lamps inoperative or removed may result in current flow or voltage in excess of normal levels. To avoid
possible transformer overheating and possible premature transformer failure, Leviton strongly recommends the following:
a.
Do not operate dimmed transformer-loaded circuits without operative lamps in place; and
b.
Replace burned out lamps as quickly as possible; and
c.
Use transformers which incorporate thermal protection or fuse transformer primary windings to prevent transformer failure due to over-current.
For best results transformers employed in transformer-loaded dimmed circuits should be high-quality units well varnished and with an extra margin of magnetic
material.
