What am I doing wrong

[dba7108]

I had a ring doorbell transformer and it went bang the other day when I moved it. Been working for 4 years fine. It's wired in to a 13amp plug. I bought a new transfer today same one. Wired it up and it's gone bang. The plug has a 5amp fuse. The previous plug had I think a 13amp fuse. What's going on here. It previously worked for years and now it's not!

Are those wires being gripped properly?

How do you know the transformer has gone 'bang? What have you tested to confirm it?

[Doofus]

Curiously, as per a thread I made on here a while ago, my Ring was AC, but your transformer says DC. Is it the right transformer for the particular model of doorbell?

[OIC]

All the makings of a suicide plug right there.

For it be.

If it's gone bang it's the load that's caused it, not the plug.

I turned it on to test it and a spark and bang happened!

Did you have the output side of the transformer connected when you energised it?

Depends how much test kit you have...

Did you move the plug and transformer to a new mains outlet?
If so, I am suspecting that outlet (since that is the only change) - though at first thought I can't see why.

1) At the transformer end of you death lead, do you have 230VAC across L&N (when plugged in to your new location)?
2) Same voltage when moved back to the original location?
3) Is the fuse intact?
4) L&N reversed on the new outlet (shouldn't make any difference if it is a transformer - but it bay be some 'electronic transformer substitute' which might not be happy?
