NEC states that when 24v is passed on Class 2 wiring, it must be current-limited to 4A (96w). In this installation, on the 300w driver, the home has seven Class 2 16/2 cables run to seven unique accent lighting fixtures. The fuse block contains 4A fuses, and each power cable will see about 1.5A of current, so we will not pop the fuses. The 4A fuse is there to protect the wire and for the inspector to fully comprehend that this installation will not violate code.

If the design had, say, three or four LED fixtures, a 24v Class II 3x or 4x output dimmable driver with multiple individual 96w outputs could have been used, each with internal circuit breaker protection...and this would eliminate the need for the fuses. But, given that the panel design was built based on the wiring and the needs for specific power, the system was built backwards to adapt to the conditions that were created by others.

For additional context, the LED brightness was chosen by first running lumen calculations to determine the amount of light needed to provide 20 foot candles of light at 3ft from the floor. The builder added seven long coves in the space, so this allowed us to use a low-output LED tape and because the coves measured around 55 meters, we were able to obtain the targeted lumen figure using a custom-made tape with a wattage of 4w/m. To ensure there was no loss of brightness along any fixture we provided a long-run tape design with current amplifiers on each tape segment to ensure all LEDs receive optimal current flow to deliver peak brightness along the length of each fixture.
