Chipamp PSU- TP resistor across fuse??

[VictoriaGuy]

I'm just putting together some PSU 'kits' from eBay (notorious audiotek) and came across something unfamiliar.
There are two connectors (labelled TP1,TP2) which are connected to the ends of the fuse- this is on the DC side at the outputs. Included in the 'kit' is a 10 ohm resistor which the (fuzzy) pic in the eBay ad shows connected between TP1 & TP2.
So there is a 10 ohm resistor in parallel with the fuse? What's the point?
I'd appreciate any 'enlightenment' on this- mostly to satisfy my curiosity- the PSUs seem to work fine.
Thanks
John

Probably to allow current limited testing by simply removing the fuse.

If I had to design a power supply, I would simply add a jumper that decreases the current limit.

Hi,
the TP either side of the 10r allows you to measure the current during testing.

The 10r is not a good way of limiting fault current. It generally takes too long to rupture if large fault currents flow and drops too little voltage if lower fault currents flow.

A Variac or current limited lab PSU or mains light bulb tester will all do a better job of limiting/preventing catastrophic failure if there is a circuit and/or component fault.

Star and Andrew-
Thanks for the responses.

Andrew- I've got 'all of the above' here and use them as appropriate when firing up gear for the first tests. All good advice.
The 10Rs went into the parts box.

Cheers
