I've heard from various sources that the UK is 230 -6%/+10%. If the EU dictates otherwise, then I'm certainly over the 6% limit. I may or may not be over the 10% limit. While the UK is still in the EU, it would be good to get this resolved, since we will be leaving in just over 2 years. Rules in Brussels override those made in the UK, which is one of the complaints we have in the UK. But +/- 6% could actually be beneficial, if it is correct. I will be measuring at the incoming terminals some time soon. For now I have added a variac, which has lengthened the time I can hold my fingers on the 8970B from 2 seconds to 9 seconds!!! So a very marked difference in heatsink temperature since dropping the voltage.
