RCDs

you are all forgetting your MCB curves A 1A breaker will let through up to 12.5A (dependig on type of course)

A HRC would offer better protection

Hi, Sorry to join this debate a little late!

I think I'm possibly one of the longest standing users of a fully installed C-bus system (Some 2 years.) on the ukha group.
At the time of my install c-bus was pretty new and I think its fair to say there were a few unaswered questions.
The technical manager of the time a guy called Niall was NOT recomending the install of MCB's on the outgoing channel and as a result I have NO outgoing protection. Indeed the install documentation of the time makes no reference to protection on the outward side.
My proffesional electrician also did not recomend there use.
In two years I've had no problems! (Oh boy why do I feel I'm going to regret saying this!).

Now I'm wondering if I should retro-fit a load of 1am MCB's to my install, which could leave me some interesting space issues in my consumer units!


Ho hum!

P.S. Anyone reading this who is undecided about installing c-bus. Do it! It is fantastic and 100% reliable!

Barney - any pics of your install you can share with us?

Thanks

Interesting - Niall was most definately telling people to install outgoing protection 18months ago !!

Also refering to your earlier post you dont need/want an RCD protecting the lighting circuits.

Dean,
In Australia the manditory installation of RCD's on lighting and power circuits is an SAA rule applied to all new installations in domestic dwellings and other various applications.
My experience is that the inclusion of an RCD on the line side of any lighting circuit saves alot of toasting downstream of various components.
One could almost see them as manditory as their benfiets far outway their cost. I would therefore disagree with your comment as above. They not only save lives, but hardware as well.
Cheers
