Hello,
I recently bought a 1960s-built house.
It had an electric storage heater in it that I wanted to remove. A notice on the heater said to remove the bricks before undoing the wall mounts so I went about taking the bricks out. This was fine for the layer in front of the heating elements but...
Hi folks new to this but have a question . What are the circumstances that have to be met to fit a 240v fan in zone 1 . I have read that it's acceptable if the fan is ipx4 rated and is on a rcd. I've read that if the manufacturer states the fan is suitable for zone 1 and rcd protected then it is...
Hi,
I have recently been having a fault with my LED flood light in my garden. It works OK for about 3 minutes and then flickers like a strobe. If you turn it off for a period, then turn it back on again it works for 3 minutes again and then again flickers like a strobe. I have had these lights...
I've noticed some manufacturers are replacing inverters themselves rather than sending the inverter to the installer. I wonder whether this could void the warranty for some firms?
Hi All
reading the guide it mentions performance of different panels & how they react, Maybe with all the guidelines & standards we have to adopt they should have had more stringent standards on the panels in the first place & then they would not need the requirement.
Evidence has emerged...
Hi just looking for your opinions on putting an RCBO on as busbar protected by an RCD, the reason i ask is the manufacturer doesnt make a 45A MCB but does make a 45A RCBO.

Afternoon all
We have a couple of damaged Day4Energy 240w modules to replace and so far as I can tell this company no-longer exists. Well not in the same form as it did a few years ago anyway.

Hi,
Am running a radial power circuit in 4mm fp200 with a 20A rcbo but am a bit worried about the voltage drop. I have a 70M run clipped direct and by my calculations I will need to go to 6mm. I am using table 4d2 but don't know if there is a table for fp200.
Does anyone recognise/know of the manufacturer of this bathroom extractor fan?
There are no manufacturer's marking on the actual unit
Thank you in advance

I have been asked to quote a shop fit out that will have 52x 45w LED ceiling tiles overall. they would like 12 switched at a time if possible, but on a previous job I only had 6 on one switch and had to use a 10A C-type MCB just to sto pthem tripping out on startup. I was thinking of wiring...
