Grounding and Bonding for Low Voltage? | Information by Electrical
It depends on what the "low voltage" is. Generally speaking, "low voltage" circuits don''t have to be grounded, per 250.20 (A), but again, thats a very general answer.
eCFR :: 46 CFR Part 111 Subpart 111.05 -
Conductive materials enclosing electric conductors and equipment, or forming part of that equipment, are grounded to prevent a voltage above ground on the enclosure materials.
How to Design System Grounding in Low Voltage Electrical Systems
Since ground resistances are typically low and of the same magnitude, voltage of the order of U0/2 is dangerous. Therefore, the part of the installation affected by the fault must be automatically
High Resistance Grounding (HRG) low-voltage design guide
For low voltage (600 V and below) systems, this naturally-occurring current is typically 1 A or less. When one phase becomes grounded, additional current above the charging level will flow.
