Anybody got any thoughts on this;
I've been asked to install a new 16 amp 4 pin 415v industrial socket in a workshop to supply a lathe.....seams like an easy request, however there isnt a single distribution board in the building with a spare single phase, let alone a three phase way left on it...
Hi all
Having a strange problem with some testing .
Did an installation for somebody and upon testing discovered high Ze . ( 640 ohm )
Not happy with result ( after testing all other earthing conductors to infinite ohm or higher than 640, bonding no doubt), i discovered the earthing...

I'm just writing up an EICR from last month, one of the findings was a lighting circuit on the non RCD side of the board where the cpc was used as a strapper in 2 way light switching, Ive marked it as C2 for two reasons, one being that there is no longer a cpc in the cable and also that...

Been to a Job this morning problems with RCD tripping, Global IR came back 0.016, Split circuits down and lighting tested (Including outside tested 0.018) however tested again 0.567 and then 1.03 each time the figure increases until it sits about 1.14. Testing done L&N - cpc and then N-Cpc...
Hi folks wonder if you can shed some advice too a newbie. Just started out on apprenticeship, getting tools bit by bit. Just acquired a Fluke 111 multimeter, discontinued now, but setting me up I'm not complaining! Really chuffed. Anyways, should this be calibrated regularly? Readings seem ok...

Hi,
I have just purchased a Matrix MEH601 Cooker Hood, I bought it for the purpose of recirculation not ducting. There is already a plug socket for an extractor fan on the wall so the basic electrics are already in place, however I need to replace the current plug socket with a Double Pole...
Hello Guys,
is there an acceptable safe way to add and wire in a small 35wat light from an existing light switch.
I was thinking to put the light in series but however if I do that, wont that light be taking all the amps that are passing through the light switch. at the moment that switch only...

Hi Guys,
I haven't been on here for a while and was just wondering how most people are interpreting the DTI guide 1% voltage drop recommendation nowadays?
Is the only way to be 100% sure that inverters will not ever drop out to design to 1%?
And when meeting 1% requires enormous cable sizes...
Hi,
I am doing an install where the inverter is connected to a cable feeding an existing garage CU - we have split the cable and fitted a 2 way CU for the inverter only. Cabling is 6mm which is fine for the inverter supply, however I suspect it may be on the small side for the number of garage...
Have a job where Ze is 0.36 ohms on a TNC-S with 80A BS1361 suppliers fuse. The general rule, as per OSG (page 11), is if Ze is below 0.35 ohms then this is acceptable, but that relates to a 100A fuse (OSG fig 2.1 on page 15 refers). Now I believe that this installation should comply, so have...
Guys - I am sure this has been answered but I am not clear.
I have been advised by two installers that if I have a 4kw system ie 16x250w panels I don't need a DNO providing the inverter is not capable of or is limited to 3.5kw as can be done on the SunnyBoy. He said he installs all systems...
