Re: Levell TM14 Modern Equivalent?
Isn't one of the Robin insulation testers applicable..
Used one at college in my city+guilds electrical installation course..
Measure resistance down to 0.01 ohm forget the top end tho.
Insulation test of 100,250,500 and 1000 volts..
Or one of the new Meggar units.
