As above, most decent ATX Power supply units are protected by an internal T5A or T6.3A fuse but there are exceptions with some unbranded models!
The voltage selection switch if in the 110/120V position usually results in a loud bang followed by plumes of white acrid smoke as the smoothing...
How did the electrician isolate the supply to enable the new CU to be fitted safely?
If there is no double pole isolator fitted between the meter and CU I assume the main cut out fuse was removed after breaking the seals?
Before refitting the cut out fuse were the terminals checked and the fuse...
Please elaborate, non contact probe/voltstick to check cut out fuse is live, same device on meter tails (conductors) and CU. Socket test is always at the same one beginning and end of installation, if it tests correctly at the start it should, if the polarity is still correct, retest correctly...
The correct procedure is to check for correct polarity at the cut out and meter connections using a none contact voltstick, then check for correct polarity at the CU using the voltstick across the live busbar or MCBs and then use a socket tester to confirm at a socket. After installation of the...
My mistake,please accept my apologies, I can’t wait to explain to my next domestic customer the benefits of saving energy by replacing all their luminaries with LED fittings.
I would give your electricity supplier a call ( the one that sends you the bill) and ask them to come out and inspect your meter as you feel it is unsafe.
Given there are 2 load tails connected to each terminal I would imagine there would be copper showing and to physically get 2 cables in the...
Not only is the reverse polarity a serious meter installation fail it would appear from the only photograph shown that the cut out tails appear to be 16mm on the neutral and 25mm on the live, another fail.
All black cut outs are also reportable to the DNO as a MOCoPA C17 code as their...
A Hepworth clamp is NOT suitable for attachment to a lead sheathed service cable!
Please bear in mind the protection device for this cable will be located within the sub station and it won’t be a 13A plug fuse!
There are 2 types of clamp that may be used...one is a crimp type which requires the...
Could you please explain to me why after having a Smart meter fitted your bill will increase?
The Smart meter is fitted on exactly the same tariff as the old classic meter so the unit price and standing charge are exactly the same.
It is certainly an untidy job, the cable should be terminated using a 3 finger boot and heat shrink on the conductors.
Connection directly into the meter load terminals should be avoided by fitting a KMF and meter tails /earth to it then connecting the split con to the load side ensuring the...
