In the (16th ed) OSG - the 17th is still on back order at Amazon
- section 10.3.3.1(i) it says
Quote: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?
