Question about Electronic Specialties ESI 385A Digital Engine Analyzer & Multimeter
I am installing an Underfloor heating System (Heat Mat) of 7mm cable.
The 3 core cables are black, blue and earth.
Is the Black cable live when connecting to the thermostat.
Yes! The blue is the Neutral or MP. Black is the active wire.

European color codes are black or brown for hot, blue for neutral, and green-yellow for earth or ground.
