Does operating frequency affect the issue?
If the radar system is in an official ISM frequency band, use CISPR 11, but if
operating outside the those bands treat is as an RTTE device?
Also, what about the market served? The original poster seems to have a

There is a SASO standard for power outlets and plugs. However, I do mot have

references the UK BS 1363 plug and the US NEMA 5-15 plug. Also, to the best

Alternatively take the output from the Variable Voltage Transformer (Variac
is a trade name) to a good quality isolating transformer - then you have all
the low leakage you want. (Remember inrush currents.)

Only about your first question:
The values of temperature rises of table 16 are based on a temperature of 25
degrees, see sub-clause 1.4.7. A rubber handle can have a max. temperature
to touch of 25+50=75 degrees (not 85).
You will feel that the rubber is warm. If the handle is made of
