Fw: CBus Dimmer Compatibility

[Gareth Cook <g@xxxxxxxxxx>]

Ditto.


Hi Paul

Yes, each dimmer is protected with a 10 amp C curve on the input
(couldn't get 8 amp!) and 1 amp B Curve on the outputs.

Regards

Neil

consensus was that it's a good idea to protect the dimmers. Ben A did my
install and put them on each channel output as well as on the input to
each dimmer unit. Costs a little more but worth it.
