Insulation resistance tests and RCDs
Jul 9th, 2008, 3:41pm
 
In the (16th ed) OSG - the 17th is still on back order at Amazon  Angry - section 10.3.3.1(i) it says

It should be confirmed that there are no RCDs incorporating electronic amplifiers, before the test is made


Do all RCDs incorporate such amplifiers? If not how do I tell if a particular one has an amplifier in it? Or should I just play it safe and assume that they all do?
