Diagnostic Troubleshooting Tips

•

AC charging concerns should be checked with customer-supplied charging hardware (supply cable, ICCPD,
and vehicle cable, for example)
•

The infrastructure that supplies customer homes and garages often differs from the infrastructure
in a Porsche Center or other commercial building. For example, customer homes are typically
single-phase and operate at 240 VAC, whereas commercial buildings are often three-phase and
provide split-phase to 208 VAC circuits and receptacles in the workshop. This change in operating
voltage affects AC charging hardware operation and overall charging power, for one.

		•

Ground Faults
Underwriter Laboratory (UL) requirements define ground
fault and residual current detection capabilities for EVSEs.
By design, ICCPDs are extremely sensitive to ground
faults in the supply infrastructure.
The self-test function of typical residential GFCI receptacles
can cause ground faults. GFCI receptacles or circuits are a
common code requirement, especially in residential garages
and damp or wet locations.
A qualified electrician may need to ensure the quality of the
complete electrical system grounding and bonding (metal
