NUISANCE TRIPPING DUE TO EARTH LEAKAGE

THE PROBLEM & SOLUTION...

The tenant of this rented property has suffered with reoccuring damp issues in their bathroom over a long period of time. The owner asked us to install an extractor fan with a run on timer to alleviate the problem of excessive moisture.

The position of the new extractor was identified on the inside and a pilot hole drilled so we could confirm the position on the external face was suitable.  It was not posible to obtain access to the outside of the building due to the location of permanently installed car port.

We drilled a 105mm hole through both skins of brickwork using a diamond tipped core drill, then utilised an internal fit extraction vent kit. This allowed us to install the external vent from inside the property. The fan is installed after the external vent has been positioned and fitted.

Bathroom Extractors are usually wired to the upstairs lighting circuit. On identifying the circuit it was evident that there were shortcomings with the existing connections in terms of fire safety. These were corrected during the installation and all conductors placed into a Wago junction box.

The new 3 core & earth cable runs from the lighting circuit to a 3 pole fan isolator before continuing on to the fan. The isolator breaks the line, switched line & neutral conductors.
