    32A commando socket without isolator

    Any issues with installing one of these without an isolator? The D.B is about 3 meters away and the commando socket will be mounted under a kitchen worktop for a coffee machine and there isn't enough room for an isolator.

    16mm SWA tails maybe 9 mtrs from isolator on a 100a supply, and other concerns - EICR opinions

    This has come up many times before and after a couple of hours reading previous posts I'm no closer to deciding on a code, note or nothing at all. BS7671 allows 16mm tails on 100A fuse if demand is less than the cables CCC, I have 16mm at 94amps and the max demand is 60a. From a previous post...

    Bno Supply - Isolator

    Hi, I am quoting the switchgear for a BNO install. I have only worked on MEM (Glasgow) isolators but was looking at the contactum TPN 200amp isolator as another option. I need some advice, if I should stick with the MEM. I will be terminating 95mm in the isolator after the UKPN cutout.

    Isolator when inverter is remote from consumer unit

    I have never done PV but a customer has had a system installed and has a few issues with it, most of which are being sorted out. I have a question, should an isolator be positioned next to the CU when the inverter is in the loft ? I have never seen one without, and had advice from other...

    Rotary Isolator that takes 2x16mm?

    Does anyone know of a rotary islotaor, weatherproof, that'll take 2 x 16mm incomers? I've got long runs out to parking bollards so they've had to size up the cable for volt drop. I could do it with a street light cutout but it wouldn't allow them easily isolate it. Many thanks for any help.

    100A DP Isolator Installation Between Meter and CU

    Hi guys, When installing a new CU does anyone ever install a 100A double pole isolator switch between the meter and the consumer unit? Very often I come across 16mm tails which need to be upgraded to 25mm so I join the old tails to new in a Henley block and get the DNO to come and upgrade...

    Fan isolator switch access

    I have attached a photo of an isolator switch which is for an extraction fan in my kitchen. The only way I have found to switch it off is to take the front plate off which then gives acces to the switch. Is there a key/tool that can be used to turn the switch off/on through the slot in the front...

    Need help with wiring a fan isolater, testing unit possibly broken.

    Hi, I had a problem with the fan isolator in the bathroom and it cut out. So I had a look at the switch and replaced it. But that didn't fix the issue and I am wondering if the unit itself has gone. Is there a way that I could test it? This is how the switch was wired. And this is...

    Bad experience having isolator switch fitted by Scottish Power/Actavo

    I "recently" contacted my DNO to have an isolator switch fitted beside my meter (my consumer unit needs changing and I didn't want to pull the fuse). I was told I needed to contact Scottish Power who charged me £85 but failed to turn up for the appointment, resulting in me having to contact them...

    Fan Isolator switch alternative

    Hi. Random question, but in our utility room we have an extraction fan like what is normally found in a bathroom. Currently doesn't come on with the light or anything like the bathroom one.

    Isolator versus protection device on main incomer

    Hi, i'm only a student so please forgive me for the basic question: Say you have a generator or power transformer serving a main mccb panel, why can't the main switch of the panel be just an isolator? I've only seen the main switching device as a mccb or acb. I know that in a house you'll have a...
