I have an inverter (Victron Multiplus 2 48/5000) that is currently fed from a 50A RCBO however it doesnt give me any selectivty when downstream circuits fed by the 30ma RCBO's trip, so I would like to swap these out to MCBs and potentially give additional protection via 100ma / 100ma Time...

I'm wanting to provide isolation for an inverter for both the AC in and the AC out(s). Rather than having big bulky 80a rotary isolators next to the garage CU (potentially with minimal space inside the isolators for wiring), is there any reason why I cant just add a small 4way CU next to the...

I am toying with the idea to install a "non standard" socket next to my CU on a circuit that will not be RCD protected. The reason for no RCD protection is because the appliance is a calibration checkbox with RCD testing and requires it being powered from a non RCD protected circuit. Hence the...

Boiler maintenance/repair company already notified and due out Thursday (providing my claim is valid for the policy) I am just asking for clarification/confirmation so I know what to expect. If the flue seal part cannot be answered due to fear of DIY please omit this question. Long post so I...

My oven decided to give up and the fan oven heating element has failed (IR: 0.16-0.29MΩ @250v). While taking it apart to test I notice this element had an earth terminal but no earth connection, I decided to test the grill element while I was at it (all ok) but noticed this element is earthed...

I am in the process of doing some radiator replacements in my house + other bits. I have changed several single radiators for some new double panel/double convertor radiators. So far its just 3 over a period of a few months as I got round to those rooms. The system has been drained once or...

I called the DNO for my area yesterday afternoon to enquire about what earth arrangements my area might have. The lady just said your electrician will know as we don't. The reason for me asking them is it doesn't appear I have any main earth. It looks like I have some supplementary bonding but I...

I need help in working out what 12v power supply I need to purchase if someone would be so kind to help me get my head around calculations. I have some 12v dc to 5v usb converters that I will have around the house in some media back boxes and am looking at a central 12v dc power supply. the...

on a house I recently bought and am doing up I suspect I have a leak on a Yorkshire fitting on the central heating main feed pipe upstairs which is almost impossible to get to. I can just reach it with my hand to feel the joint and it does look like a tiny bit of water is coming out when I run...

I have just purchased a place and would like to take out the noise maker that the previous owners had installed. currently the setup isn't the most ideal config in terms of sensors, locations etc... so I will be replacing all this. I also will be adding some form of personal alerting to...

Hi Guys and Gals, Got myself a first home and already have started to destroy the place (rewiring all the electrics) so while carpets and floorboards are ripped up and running electrical wires in walls it seemed like the perfect time to start my home av/automation project :mrgreen: Although...

Hi Guys, I am in the middle of fitting all new sockets and media outlets and have a quick (I hope) question. for downstairs the load bearing wall is a single brick wall, not sure of the depth of the brick. For my media cables and modules it is saying that the back box depth needs to be...
