Variateur à la terre Inverter Grounding

The equipment grounding conductors in a system are normally uninsulated (bare) conductors that are grounded. They are intended to carry currents only during fault conditions and are the last line of defense to protect the user from short circuits in equipment. When these equipment grounding conductors are improperly connected, currents can and do flow in these bare conductors (during non-fault conditions) posing a safety problem. When
currents flow in these conductors, shock hazards can exist and equipment damage is possible. At the very least, electronic equipment such as TVs, stereos, computers, radio telephones, and PV instrumentation and control
systems may not work properly. PV systems are easy to connect, but they can also be connected in a manner that allows currents to flow in these
equipment grounding conductors. With the presently available equipment, it is sometimes difficult to avoid the currents. The National Electrical Code (NEC) specifically prohibits connections which result in these currents and
requires that actions be taken to eliminate them. The Equipment — Load centers An uninsulated copper or aluminum bus bar is installed in
most standard ac residential load centers (circuit breaker box). This bus bar is fastened (electrically connected) to the
