Lewden 30mA type A RCBOs

[andrew8902]

Happy new year guys,

I installed a new Lewden CU today and all the type A RCBOs failed when tested at x5 (150mA) at the end of the circuit. However, when tested at the terminals of the RCBO they tripped in around 38/39ms. I am aware that Hager have had issues with their 61008 RCCBs and suggest testing them with 250mA test current, are they any know issues with Lewden switchgear?

Thanks

Never had a problem with Lewden kit but I always find it easiest to test at the device with the cables removed.
