Books Allowed in the Exam

Buy at Amazon
2.
Ugly‘s Electrical References, (any edition), George Hart
Buy at Amazon
3.
American Electricians‘ Handbook, 16th Edition (15th out-of-print), Terrell Croft, Wilford Summers
Buy at Amazon

NOTE:  You have to option to use either reference #2 or #3 listed above for your study material.

We recommend that you purchase a current version of reference #3 (16th) because the 15th edition is (apparently) out-of-print and some sellers want $350 for a new copy.

Additional Recommended Books

1.
Ferm's Fast Finder Index, 2014, IAEI
Buy at Amazon
2.
Tom Henry's Key Word Index, 2014, Tom Henry
Buy at Amazon

We highly recommend that you purchase one of the reference books above to study for your exam.  Each book is a comprehensive subject index to the NEC.  They provide an even faster way to look up answers in the code and are far more detailed than the index at the end of the code book.
