Re: Updated pics of my loft conversion



As Paul said, the C types don't trip so quickly as type B. That's why
I used them. Under suitable conditions, they'd go as well, but
I already have a type B MCB on the input to each dimmer and on the output
of each channel. If anything is going to protect the
triacs at all, then they should be able to do it.

It should also be said: I'm not a sparkie.
