Rated 5 out of 5 by from good product Good product fitting nicely on the board. Quality is good
Date published: 2021-03-01
Rated 1 out of 5 by from Randomly trips and no reset Had two of these 20A RCBOs and they have both failed in the same way in less than a year. It starts by randomly tripping. Leaving you thinking you have an earth leakage fault somewhere. Then it will eventually trip and you can't reset it - unless the power is off! Apply power but no load and it still trips. I've taken it out of the dist. board and put it on the bench with just a mains input connected and it trips as soon as power is applied. When it does this you can't reset it. It's a shame as I love BG products.But with two failures (original and replacement) I now don't have the confidence to replace it with a third unit. It is for a broadcast-critical power supply and the last thing I need is to lose power in the middle of a broadcast.

Asked by: les1946
Hi les1946, Dimensionally all consumer unit devices are pretty standard sizes, but the thing you need to be careful of is a line in the 18th Edition Wiring Regulations (BS 7671:2018, clause 536.4.203, Note 2) which says that if you mix manufacturers you become responsible for any warranty as you have made yourself the original equipment manufacturer by this action.
