Will most testing locations let you take the NEC Handbook in as opposed to the normal Codebook?
mdshunk said:I have taken 7 tests so far. In each one, they only permitted the code book, and not the handbook. Sometimes you are permitted to take in handwritten notes in addition.
230.2 Number of Services.
A building or other structure served shall be supplied by only one service unless permitted in 230.2(A) through (D). For the purpose of 230.40, Exception No. 2 only, underground sets of conductors, 1/0 AWG and larger, running to the same location and connected together at their supply end but not connected together at their load end shall be considered to be supplying one service.
The basic requirement of 230.2 is that a building or other structure can be supplied by only one service. However, under certain conditions, when a single service may not be adequate to supply a building or structure, 230.2 permits the use of additional services. Sections 230.2(A) through (D) describe those conditions under which more than one service is permitted. If more than one service is installed, 230.2(E) requires that a permanent plaque or directory be installed.
