Samples for Grounding
There is two of samples for grounding below.
Using a grounding wire
•Determine the size of an external ground wire according to Article 690.46, NEC2014.
(Equipment grounding conductors smaller than 6 AWG shall be protected from physical damage.)
•A grounding conductor with insulation or bare (no insulation) may be used, provided the terminations are reliably available.
Grounding wire
AC junction box
Using listed EGC
• Use equipment grounding conductors approved by Article 250.118, NEC2014.
Bonding jumper
EGC
(ex. metal rack)
grounding wire
AC junction box
•LG AC module includes DC cables in the module’s internal wiring, so no grounding is required for DC input.
•For equipment grounding, LG AC Module uses an external grounding equipment conductor. AC cable does not provide a grounding conductor, grounding is provided only by the external connection to the module frame.
