    Upgrading my service from 60Amp to 100Amp

    Either you or your electrician need to contact your dno to ask about increasing the supply fuse, neither of you are allowed to make this change, only your dno can. In my area you will only get an 80A max and that is if local network demand allows this. Whilst under our regs 16mm tails shouldn't...

    Milwaukee M18 Fuel!

    If you are impressed with the Milwaulke fuel 18V impact driver, wait until you use the Milwaulke 12V surge impact driver. It is hydraulic, quiet, controllable and powerful. Cracking bit of kit, only problem with it is that I now have a spare 18V impact that no longer gets used

    PME Supply Advice

    You do not link the E to the N, we are not allowed to do that. Whole thing sounds unusual, first port of call should be a call to the dno with an earthing enquiry. In my area they are extremely helpful

    UK Shared income supply main fuse

    Are you an electrician? Looped (shared) supplies are not uncommon although your cutout is not one that I recognise. From the photo it is impossible to tell whether the feed to next door is taken from the supply side of the fuse and then fused next door or if it is taken from the load side...

    Becoming an electrician

    I am the dad of a dno band 5 technician (plus an electrician myself). Career progression within National Grid now effectively requires a large element of technical qualifications (HNC etc) which you sound ideally suited for, you can study whilst working. I find what my son does quite...

    Gas meter 'vs' SWA cable proximity

    Pretty sure there is a gas reg that states the gas shouldn't be within 150mm of the electric incomer, other than this instance I think the 25mm guidance applies. I was told that these rules are to do with arcing which is unlikely to be an issue with swa

    What is wrong with my new TV ariel Installation plz?

    If you are not lucky when adopting the 'just put it up and see what happens' approach then you will (ideally) need a uhf signal meter. As Brian correctly states above, it is not just strength that is required, the signal quality is paramount. Have you got the polarity correct (flat for main...

    Isolators in meter boxes

    Now I know I have family connections with NG (Western Power as was) but I have just formally asked them to quote for replacing a surface mounted cabinet with broken hinges and broken fibreglass where it should latch, it is an unusual cabinet in that it is not the type that is currently used or...

    Long cooker hood duct ?

    Hopefully you have a straight run. The most efficient duct to allow the passage of air is smooth walled and straight and I would use as long a length of 4" soil pipe as I could. This should be installed with a slight run downhill towards the grille Cooker hoods usually have larger than 4"...

    Condensing extractor fan

    I have installed a few PIV systems. They are more whole house solutions than single room solutions and they are suprisingly effective. Both nu-aire and vent-axia, to me the only difference appears to be price. I have only put in one whole house heat recovery and ventilation system, it gives...

    Product defect or installation error?

    Was this a flex termination or solid conductors? I always ferrule flex terminations and use 1.5mm 3093Y for immersion connections

    UK How to go about adding a secondary router/wifi hub

    Sky have their own equipment within the exchange so it is not just swapping over a router, alterations have to be made in the exchange I recently did a 4G system as BT could only offer 4mbps fibre. Very poor area for mobile signal as well but by using a 4G aerial in the attic and having the...

    Water cylinder thermost question

    I have a customer who has an 18" thermostat in their water tank which periodically requires resetting. I went to replace this but am unable to put a new 18" one in as the tank is very close to the ceiling and the thermostat is withdrawn in an upward direction. I can get the 18" one out by...

    Retractive switch question

    An 80A supply is now a 100A supply- discuss

    Locally most supplies are 80A. The stated reason is that the supply agreement is for 15kVA and an 80A fuse is the nearest to this, a 60A being under the 15kVA the agreement states they must supply. However it is dno policy to change any 100A fuses for 80A as there have been instances of the fuse...

    2 supplies to single building

    I recently had similar but my 2 supplies were from different transformers going into different ends of a long property divided in two. Western Power were ok with this and with it being PME as long as the two sections were completely electrically seperate. Unfortunately they shared the same oil...

    DNO fitted New Incomer etc . How long can we expect for supplier to fit new meter etc . ?

    Was it a smart meter? The DNOs can reconnect but they are not allowed to move smart meters, they are allowed to move standard meters though. A fairly recent rule that they are not very impressed with!

    H.V. Ring Main

    There is actually a fair bit more to this than one might think at first. There have been occasions when he has had to isolate different sections of the 11kV network and power them by step up transformers, instead of 11kV down to 400V as is usual these are 400V to 11kV. As regards to spiking he...
