[TG] ACU-150 & EV-1 Location & Questions

[Tom - Raymarine - Moderator]

Hello kingspade,

I'm sorry to say that we, as the manufacturer, can't give you any other answer than that that product must not be mounted in an engine-room or similar. We have a legal responsibility and duty-of-care to make this clear.

To answer your question: the ACU150 in particular is switching large amounts of current, and neither is in an intrinsically-safe enclosure. That makes them a potential ignition source. Of course they ought not to spark, but then every airline crash and every boat fire is as a result of something that wasn't supposed to happen. You can't afford to talk about what's likely but what's possible when considering fuel vapour fires...

I would never install any product marked like this in an engine-room on my boat.

Regards,
Tom
