ground wire
ditch
footer
When installing a grounding system, keep the basic components in mind. Consider the soil condition where the system will be installed. You will have to create a ditch (fer una rasa) to install the system. A ground wire (cable de terra) is a typical part of the system. Also, bonding wire (cable de connexió) and a footer (pica) are important elements. You must aware of resistance between terminals. You should know the current level (nivell de corrent) that will drive through a wire (conduirà a través del cable).
