A few years ago we had wood floor professionals extending power cables underneath the floor as part of an overall floor renovation.
We only recently learned that they used screw terminals which could be problematic when placed in inaccessible locations (such as under a wooden floor).
Our main concern is the fire hazard and it seems like we have two options:
- Open the floor and re-wire everything - that would require re-finishing the entire floor to achieve a consistent look.
- Install AFDD switches as mean to protect against fires.
I understand that option #1 is the best option. My question is how reliable AFDD switches are in this case? is option #2 good enough (realistically)?
