Hi there,

Is a fuse or circuit breaker recommended on the primary power cable run from the battery to a PDM? If so, can anyone recommend a suitable solution?

Thanks in advance!

Nico

I don't think that is necessary. A properly setup PDM will limit the total current long before any large fuse could react.

Thanks David. It's great to get advice from someone who has been there and done that. I really appreciate it.

Agreed, the PDM is supposed to replace the fuses normally required - what I would suggest is a master switch (manual or solid state) to kill everything - but you probably already have that installed.
