Essential if you plan to pass the C&G Exam- By: jnib, 05 Jul 2006 This book will never win a prize for literary content, but if you're going to get serious about Portable Appliance Testing it's this season's must have & it will get you through the C&G exam. Somewhat expensive (hence 4*s) - to be expected maybe? - electrical engineers are probably not best known for their writing skills so there must be a rarity premium. Tells you what you need to know & lots of stuff you don't - hardcore information & good for insomnia too. The Amazon combo deal including this title & "PAT - Portable Appliance Testing: In-service Inspection & Testing of Electrical Equipment" by Brian Scaddan is excellent & gives you the only two documents you really need. Well worth the money.
