For China CCC, there is no 2500m, 3048m, only 2000m and 5000m. So you have the choice to add the altitude symbol to show the using condition is below 2000m, or you can test the clearance distance to meet the higher altitude requirements. If you are certifying a product with CCC certified power supply, the power supply need to be approved to the new GB4943 standard first. If the power supply can be used below 2000m only, the end product also need to declare the 2000m altitude.

You may know this, but I just want to point out- your product does not have to *function* at 5000m, it can shut down for OT or whatever, they just seem to want the spacings set for 5000m. You also have the option of labelling with the "no mountains" graphic if you can't get 5000m spacings.

By default you get 2000m, how many of you used different levels? This is driven by 5000m CCC requirement and some critical power supply component limitations. If there will be enough responses, I’ll send back statistical breakdown.
