This Article covers general requirements for grounding and bonding of electrical installations, and specific requirements in Section 2395.1(a) through (g) below.
(a) Systems, circuits, and equipment required, permitted, or not permitted to be grounded.
(b) Circuit conductor to be grounded on grounded systems.
(c) Location of grounding connections.
(d) Types and sizes of grounding and bonding conductors and electrodes.
(e) Methods of grounding and bonding.
(f) Conditions under which guards, isolation, or insulation may be substituted for grounding.
(g) Connections for lightning rods.
NOTE: Circuits are grounded to limit excessive voltages from lightning line surges, or unintentional contact with higher voltage lines and to limit the voltage to ground during normal operation.
NOTE: Conductive materials enclosing electric conductors or equipment, or forming part of such equipment, are grounded for the purpose of preventing a voltage above ground on these materials.
(Title 24, Part 3, Sections 250-1 and 3-250-1(g).)
NOTE: Authority cited: Section 142.3, Labor Code. Reference: Section 142.3, Labor Code; and Section 18943(c), Health and Safety Code.
