Will this fit a mem consumer unit

Asked by: PGCS
Hi PGCS, Theoretically all manufacturers' devices are broadly the same dimensions, but we have not had any rival products in for testing so cannot guarantee cross-compatibility in any way. Also, the 18th edition specifies that by mixing manufacturers the installer becomes responsible for any warranties.

Will this fit in the garage consumer unit

Will this fit in the BRITISH GENERAL 5-MODULE 3-WAY POPULATED GARAGE CONSUMER UNIT (1926G) that you also Sell here :) ?
Asked by: Paul080291
Hi Paul080291, Yes, all BG devices (MCBs & compact RCBOs) are the same size so will fit any BG enclosure with a spare module way (such as the indicated Garage Unit).

Do you have to replace the unit after its tripped so many times, and if so how many?

Asked by: Nick1994
Hi, thank you for your product enquiry. BG MCBs do not have a designed or advised maximum number of trips before needing to be replaced, but if you are experiencing repeated trips over a relatively short period of time then this may indicate a potential fault with the device so at this stage it may be prudent to replace it.
