RE: CBus Dimmer Compatibility

[Paul Gale <groups2@xxxxxxxxxxxxxxxx>]

Neil,

Have you got any breakers on the outputs of the CB dimmers? The common
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.

Paul.
