Three wire cable runs between the switches and the outlet. In the wiring diagram tnc 230v 400v show two drivers who leave pen.

Types Of Earthing Systems Used In Electrical Installations
Tnc switch wiring diagram. 3 way switched outlet wiring. For mfj 8621 31 vhf dataradio transceivers with 5 pin din data io connector. Interface diagram for aea pcb 88 to mfj 8621 31 vhf dataradio transceivers with 5 pin din data io connector. In this diagram two 3 way switches control a wall receptacle outlet that may be used to control a lamp from two entrances to a room. Now the tnc switch should return to neutral positin due to spring action. For sections of the pen.
But let say at the same instant the tnc switch spring fails and due to which the tnc switch does not return to neutral position but gets stuck at the close position. The source is at the sw1 where the hot is connected to. This circuit is wired the same way as the 3 way lights at this link. 10 mm ² copper aluminum 16 mm ² for sections of lower electrical conductors must change tns. Lets say tnc switch is turned to close postion the positive is extended to closing coil. It would be better to make a bridge over the mass of the receiver to show that the protective conductor has priority over the neutral conductor.
Pcb 88 is an internal pc tnc card with dedb9 radio interface connector. Learn how this truth table illustrates the manual or automatic contact positions of two contact selector switch. Mfj dataonly transceivers to various tnc. Contact position on a selector switch can easily be illustrated using truth tables.
