| General | Current and voltage are determined by the plug used. |
| General | |
| Note | In plugged-in condition, the most unfavorable paths of the entire plug-in connection are decisive. |
| When reconnecting the conductor, you must make sure that the section of the conductor already used for contacting is cut off again. | |
