I have a 3amp fused spur. Off this I have a transformer to step down to 12v dc 3A.

I've got 2 devices plugged into this transformer, one has 2.5amp on the label, the other has 1amp on the label. Would I be right in assuming these are standard running amounts and so will immediately blow the fuse? If so, what would be the approach to accommodating these devices? Increase the 3amp to something bigger and add a new transformer?

Thanks in advance
 
A 3A power supply will run hot and fail early if you are drawing 3.5A from it for an extended length of time.

Remember that 3A is the output of the power supply at 12v
The fused spur is feeding the Input of the power supply at 230v
This roughly equates to a current of 0.2A from the fused spur.

So the fuse will not fail.
