Hey guys, I’ve got to remove some electronic air filters attached to a wall. They’re hard wired into fused spurs. Is it safe enough for me to isolate the power, remove the face of the spur, disconnect the filter wire and replace the face? This will leave a fused spur with live wires from the circuit but with nothing hard wired in. Is this no different to a 3 pin plug socket without anything plugged in? Thanks.
