Does anyone know where the halogen restrictions for wire insulation in the
EU come from? I remember dealing with this issue sometime in the last few
years, but now I can't remember where the actual requirement came from.
Also, does anyone know if the Halogen restrictions only apply to, say,
Hi John:
True SELV . requires double or reinforced insulation from hazardous

circuits to be earthed (see 2.2.3.3 of IEC60950:1999 or

You may come across some distributors in Norway asking for DI or RI

That's because Norway uses the 'IT' power distribution system, where

Hi John:
Y-caps have enough margin to easily withstand
the 4300 V dc without damage.
Without immediate failure, no doubt. But such a huge overstress may
cause latent damage that later results in failure, and, since IEC 60384
doesn't call for such an over-voltage test,
