I’m doing renovations to my house and requested electrician to pull a new neutral wire to individual switch, but i’ve few questions as following:
Electrician suggested to pull a new neutral wire from electric box to switch directly (without connect any lights). Does this work properly with smart control? or the neutral wire must pull from existing lights back to switch?
Does neutral wire can share to more than 1 switch box. e.g. after i pull a new neutral wire from electric box to switch (3 gang), can this neutral wire share to another switch box beside current one (for save cost).
