42amp output? Yikes!... It must be the size of a toaster!.... Maybe you mean 4.2amp? What was it's intended use?... If it is indeed a 7Vdc output it will be fine... the high Amps are irrelevant as the device draws what it needs... It's the other way round that would pose a problem (not enough amps)...

It's not a battery charger, right? Because that won't work...

Thanks @Richard R its definitely 42A I got it from a car boot sale so not sure what its original purpose was. @DJ Sures thanks for the link, but it didn't work?

Oh dear I posted before marking as resolved :-)

A 15A 230v load shouldn't be connected to a 13A outlet. Under full load conditions it'll be pulling over 3Kw and over the 13A limit for a socket outlet. I've seen sockets melt because of high loads (granted they were in a commercial kitchen), did it come with a 3 pin 13A plug top?

@Rich.... Jeez dude you catch everything. Seriously good point....In North America house wiring is generally rated at 15amp max....

I work for an electricians so its part of one of my many jobs to catch these things. I just spent 3 months doing just that.

Hi all,

this is a sealed plug and adapter (like you would find to charge a mobile phone), you have got me worried about using it now.

i will post a pick when i get home, to settle it :-)

thanks for the interest and discussion.
