The floater concept, appears to be one solution, for a degree of protection.
Unfortunately this will not be widely known by most homeowners.
This is again, the trend to deal with the effect, and not addressing the cause.
There is many more residential occupancies that have 60º insulated wires, than 90º.
I only hope it is not an epidemic of home fire causes.
I feel the manufacturing industry can provide a solution, to preventing the cause.
