@Georges - We do have a large library of changeable labels to choose from, if there is no defined label list then not to worry as this will not impact the standardization of the panel itself once decided.

I would like to see this 3-way switch you refer to for your lighting, please let me know if you could send a picture as I beleive we could provide an equivalent solution.

Regarding the meters. The right most digit of the VOLT METER is 1/10th of amps and the right most digit of the AMMETER is whole amp. The accuracy of our meters is ±1 count.
