There are a few options for installing smart switches without a neutral wire but first lets check to see if you have a neutral wire. The earth electrodes to be inter connected to reduce earth resistance.
If My Heat Pump Does Not Have A Neutral Do I Still Need A
Why do you need a neutral wire. Is that white or black wire. Switch says common wire. Under balanced conditions the vector sum is zero and therefore the neutral current is zero. The purpose of the neutral wire is to complete the 120volt ac circuit by providing the path back to the electrical panel where the neutral wire is connected and bonded to the earth ground. Neutral conductor of a 3 phase 4 wire system and the middle conductor of a 2 phase 3 wire system to have minimum two separate and distinct earth connections with a minimum of two different earth electrodes to have the earth resistance to a satisfactory value. Modern thermostats with wi fi and backlit display by contrast need a steady supply of juicethe c wire or common wire enables the continuous flow of 24 vac power to the thermo.
The white wire is the neutral wire. It provides the return path for the current provided by the hot wire. Stack exchange network consists of 177 qa communities including stack overflow the largest most trusted online community for developers to learn share their knowledge and build their careers. Back in the olden days thermostats were simple onoff devices that didnt need their own continuous power supply. The neutral is an insulated wire because it is part of the circuit which flows electrical current. It remains has power when the switch is in the on mode.

The neutral wire allows the completion of the circuit and the switch to have power even when its turned to the off position when you want the lights off. Without this neutral wire in place the circuit is broken any time the switch is now in the off position. The copper wire is called the ground wire because it is connected to the earth either directly or through another grounded conductor. The neutral wire serves as common return to all the three phases acting outward from n 1. Therefore the total neutral current is the vector sum of the three line currents.
The grounded electrode conductor. One common problem for new smart home users is that they want to install some smart switches to control lighting but their existing light switches dont include a neutral wire.
