Metal battery box ?

[Boo2]

Hi,

I've been told that in order to put a battery in the engine compartment it needs to be in a metal battery box, allegedly due to a risk of explosion. Can anyone confirm or deny this, and if it is true then where can I buy such a thing ? (I can find lots of battery boxes, but they are all plastic.)

Thanks,

Boo2

Metal is a conductor that makes no sense.

I've never seen one and definitely wouldn't want one on my boat. Too much risk of shorting tools to the casing and shorting the terminals out. Stick with plastic industry standard (or wood if you're really old). I'd be interested to know where the info came from. I' be never seen that written down in any of the standards I've seen before.

Suggest to review the competence and knowledge of the source of your information - meanwhile ignore them.

Certainly no reference to confirm that in BS EN ISO 10133:2012: Small craft. Electrical systems. Extra-low-voltage d.c. installations, personally I would be concerned about any acid spills causing corrosion over time, not to mention the conductive nature of such a box. Sounds like yet more ill informed "dock talk" to me.

I agree with the abve posts.

You are unlikely to have access to the document that David2452 refers to.

I therefore suggest that you look at Chapter 3.1 of the Boat Safety Scheme http://www.boatsafetyscheme.org/media/180428/bss guide 2005 complete web.pdf. No mention of any such requirement there but some other points worth noting

Some regs (not sure if it's MCA coding, RCD, or BSS) require metal bowls on fuel filters instead of glass or plastic. Your source has either misremembered, or incorrectly extrapolated this to batteries on his own.
