of the terminal base must be taken

into account to verify the intrinsic safety.

Simple apparatus is defined as a device which neither generates nor stores

more than 1.2V, 0.1 A, 20

μ

J, or 25 mW.

Wiring methods must be in accordance with the National Electric Code,

ANSI/NFPA 70, Article 504 and 505 or the Canadian Electric Code CSA
