At least people can stop moaning about non-combustible CUs now. That is getting tiresome.
As the US have been using these for some time now hopefully most of the bugs will be sorted before they are finally released here. We also do a lot more in-depth testing here prior to putting a circuit into use which should help.
The EU testing has been done to the manufacturers instructions that’s how BS-ENxxxxx came about.
The US have had since 2002 to sort them out. Have they sorted them out, have they **** as like.
