Rated 5 out of 5 by from Great product Great product needed for garage consumer unit, easy to install

Rated 4 out of 5 by from Great value MCB I'm really quite impressed with BG products. And this MCB is no excdption. BG offer a good mix of sturdy, quality manufacturing with great value for money. Seriously. BG products are NOT cheap and nasty. They are every bit as reliable as even the top branded products; at half the price!! MK are market leaders, along with Wylex but you'll certainly pay a lot more for those brands the for BG. Anyway, if you're a sceptic... go on... take a punt. You'll be glad you did.

Rated 5 out of 5 by from DIY MCB replacement Worried by the review of 'Anonymous - Wirral'. The MCB should be rated to protect the cable and accessories which form the circuit. If too high a capacity MCB is installed without verifying that the circuit can handle it there is a real risk of the cable overheating under load and catching fire. At a 40 amp load (9-10kw shower would get you there) you should be looking at 6mm sq T&E minimum and that assumes the cable is installed in free air.. If in a wall or conduit it would have to be 10mm sq minimum. If in doubt ask a qualified electrician to take a look.

i need to upgrade a 32amp series E MCB TO A 40AMP IS THIS COMPATIBLE WITH THE BOARD

Asked by: alls
Hi, thank you for your product enquiry. BG Electrical has not had any GE Series E MCBs or Consumer Units in for testing or comparison so we cannot say with any certainty whether their devices are the same dimensions or have the same terminal configuration as ours, therefore we are unable to guarantee that this device would be a suitable replacement for your current 32A GE model.

MCB for 10 WAY W ylex consumer unit

Is the 32A B BG MCB suitable for a 10 way consumer unit bought from Screwfix a few years ago
Asked by: pllanet
Hi, thank you for your product enquiry. All BG Electrical Consumer Unit Devices have been designed and tested to work together with each other, but have not been tested with other manufacturers' devices or in their enclosures so we cannot say whether this would be suitable or not. Also, BG Electrical does not warrant other manufacturers' devices fitted into our Consumer Units and this may be the case with other manufacturers so it would be a good idea to check with Wylex before installing a 3rd party device in their enclosure.
