    100mA RCD on PME system

    I am going to a job this afternoon, new shower circuit. I noticed yesterday that the Wylex CU has a 100mA S-type RCD as the main switch and all the circuits are on 30mA RCBOs. PME system as far as I could tell (certainly not TT). Didn't give it much thought then, but was thinking about it...

    I am getting back into the electrical game after a few years and wondered what peoples thoughts are on the above. I am happy installing fully RCD protected DBs or Split boards but the use of RCBOs I had never seen. What are the main reasons/advantages/disadvantages for using them? I know they...

    61009-1 or 61009-2 RCBO's

    Afternoon guys, Just wondered what the difference is, if any between a 61009-1 RCBO and 61009-2 RCBO? Are the characteristics different for any reason for different applications? I noticed that 61009-2 came out 1995? Thanks

    RCD Test on lighting circuit protected by RCBOs

    Hi everyone, still training so please bear with me. What is the correct way to carry out an RCD test on a lighting circuit protected by a BS61009 Type B RCBO? I've looked in the regs, OSG and all of my course material but still no actual definitive answer so thought I'd ask here. The reason...

    Using powerline homeplugs across separate circuits

    I have just bought an Innuos music server not realising it has no built in Wi-fi capability, but needs an ethernet wired connection to the router. This could be done only by placing it in the cupboard where the router lives, whereas I wanted to place it alongside my Naim streamer upstairs. So...

    New DB loaded with RCBOs

    Could someone tell me how much you would charge for a 12way Wylex DB loaded with RCBOs as new customer has been charged £1900 which I think is a bit steep

    Need a nice to work with CU

    Seeing the PV install is going to be starting soon I thought I'd treat my bungalow to a new CU and replace old 3036 one with an 8 way RCBO board. The only RCD's in the place are the plug top type I have on the extension leads. (Only been in here for a year) I haven't had any dealings with a...

    Removing MEM breakers

    Hi folks, Well today I attended another house to perform a bathroom upgrade. Upon visiting the mains board I noticed it was a MEM. Not ideal I thought as my previous experience taught me that RCBOs were not possible with these mcbs. I then noticed that a previous spark had fitted a hager RCBO...

    Sports pavilion rcbos or rccb incommer

    Hello guys. I was asked to quote to replace a 3 phase db in a sports pavilion. All cables are twin and Earth in the wall. Because it's a building open to the public I decide to go with rcbos on every circuit, to give extra protection and discrimination so they don't lose everything if a fault...

    S-type RCBOs

    Does anyone make S-type RCBOs? For discrimination you should use an S-type RCD to protect a sub-main feeding a CU with a normal 30mA RCD or RCBOs. This can be handled with a 100mA 100mSec S-type RCD. It would be convenient if this were combined with a type B or C 63 amp MCB. This is in a...

    Any arguments against RCBOs?

    Hi, Just a hypothetical question, more of a homeowner than DIY subject. I'm kind of sorry that when our house was rewired in 2011 we didn't go for RCBOs instead of a dual RCD board, not only is the split of which circuits are on which side not ideal, but it would have saved the width of two...
