NOTES FOR TABLE 3.3 - AC OUTPUT WIRING AND BREAKERS
1)
Column 1 indicates the AC output current in "Charging Mode". When the unit is operating in "Charging Mode"
[with charging current clawed back to 0A (See Section 5.2)]
, the AC Pass Through Current can reach the value
limited by the Ampere rating of the AC Input Breaker which is the same as the programmed value of programming
parameter "GRID MAX CURRENT"
(See Section 4.5.2.2 of the Owner's Manual for Remote Control EVO-RC-PLUS)
.
As the default value of parameter "GRID MAX CURRENT" is 30A, the rated output current is also 30A.
2)
Column 2 indicates the size of AC output breaker based on the rating at Column 1.
3)
Column 3 indicates conductor size for AC output wiring suitable for 30A breaker.

INFO
Please read following on-line White Papers for complete understanding of Grounding at
www.samlexamerica.com (Home > Support > White Papers):
• “Grounded Electrical Power Distribution"
• “Grounding System and Lightning / Ground Fault Protection”
Grounding means connecting (
bonding
) to Earth Ground or to the other designated Ground. For example, in a
motorhome / caravan, the metal frame of the motorhome / caravan is normally designated as the Negative DC Ground
/ RV Ground. Similarly, all metal portions of boats and marine craft are bonded together and called Boat Ground.
Grounding is required for (i) protection against damage due to lightning strike and (ii) protection against electric shock
due to “Ground Fault”. In case of EVO™, “Ground Fault” may occur due to inadvertent contact between an energized
ungrounded current carrying conductor and exposed metal surface resulting in voltage getting fed to (i) the metal
chassis of the EVO™ or (ii) to the metal chassis of the devices connected to EVO™. When this energized exposed
surface is touched, the voltage will drive current through the body to Earth Ground producing electric shock. When
properly grounded to Earth Ground, the Leakage Current Protection Device (
like RCD, GFCI etc.
) or Over Current
Protection Device (
like Circuit Breaker or Fuse
) will trip and interrupt the circuit feeding power from the AC source
(
EVO™ / AC Input
) or the DC source (
48V battery
). Proper grounding will ensure that all exposed metal surfaces will
have equal potential and will be bonded to (i) a single common Earth Ground point i.e. the Ground Rod / buried metallic
water / gas pipe at the premises.
