Posted By Paul I Clark You will find many domestic installations isolator switches are not equipped to be locked off. Therefore the usual procedure is for the electrician to withdraw and hold the fuse, also place signage and/or a blank safety notice fuse in its place. Only competent electricians should be doing this work and they should via their specific trade training understand this.

Posted By Paul I Clark Phil, thats good news to hear, we were unable to source any for the old domestic porceilain fuse boxes found in most 1930/40's properties. This is a great developement.

Posted By Paul Skyrme leerob, I have 2 kits for domestic, commercial and industrial isolation, will look up tomorrow the make etc. BUT, and no recommendations I got them from Edmundsons. they are around £80 per kit. There IS a requirement for safe isolation, see: http://www.esc.org.uk/pd...cal-industry/BPG2_08.pdf You will find that you are NOT allowed to remove the DNO fuse from the cut out, no matter who you are unless DNO personnel (ESQCR & EAWR) Without discussing the possibility of financial fraud by having access to bypassing the meter resulting in what is called abstraction. To remove this fuse you would be working live on the "national grid" and only DNO personnel can do this at this stage, though there are plans for schemes to be put in place allowing competent persons (checked by DNO/independent body such as NICEIC/ECA/NAPIT etc.) to do this work. If you want any more detail please PM, or request again in forum. Paul

Posted By Paul I Clark As mentioned above by everyone, if a lock off system is available you should use that method as its fool proof. No one bar the electrician on the system can switch this on. However, as I stated from experience these kits are not always available so you got to consider what other options are available (although Phil suggests these are widely available for all boards now). Again, the fuse withdraw that is kept with the electrican(not the distribution suppliers main fuse), signage and removal of tails are common practices if these kits are not available. You mentioned domestic installations, so balance the risk, is it likely a different electrician is going to follow on behind, pull the signage off, reinstall the tails and buy a new fuse and fuse holder? You need to balance risk against the options available.
