Megger MFT 1552 question

[La Poste]

Greetings.
I am a little confused about the leads on my MFT 1552

According to regulations (GS38), when testing live test leads should be fused.

I don't think standard test leads on a Megger 1552 are.
Does anyone know, I cannot see any way of opening the leads up to have a look if there is a fuse inside.
They look like this:
Megger 6220-796 3 Wire lead set with prods and clips. Part No: 1001-860. Buy online or call
However when looking at Ebay I found these but they are very expensive:
MEGGER - 6220-789 - TEST LEADS, FUSED | eBay

Has anyone got a MFT 1552 and what sort of leads did you get with it
I have the large red probe which is fused but I am not sure about the three other leads.
The red/black and green leads.
Thanks.

the standard leads arent fused looks like youll need to spend a penny Try Testmeter >>>>>>>>>>> over there forum discount

the leads that come with the megger arent fused there is a 500mA in the meter and i was told they dont need to be because of the internal fuse as you cant have two in series 500mA as there wont be any diversity so it will be the one in the meter that blows anyway I know you can buy 10A fused leads for them

the ones you are looking at on ebay are here at a far cheaper price
Megger 6220-789 Fused test lead set (Red/Black) with Prods and clips (NEW) right angle plugs. Buy online or call
also you need to check if they are 10A or 500mA

GS38 compliant probes use 500mA fuses and have an appreciable resistance making them unsuitable when loop testing on live systems.

The fused lead itself will add a small variability into the test result.

Test leads fused at 10A will provide protection from short circuit faults but will not fail under normal testing conditions.

500mA Fused test leads (GS 38) order code 6220-789

10 A Fused leads order code 6220-827

I thought you maybe interested in Fluke's views on unfused test leads, this is taken from an Email received from Fluke technical staff after querying the provision of non-GS38 leads with 165x series MFTs:

[FONT=&quot]"It is Fluke's opinion that in applications using Fluke name brand instruments, fused test probes provide little if any added protection. Fluke's primary concern is that fused test probes may result in serious shock hazard due to a false voltage reading. A more effective solution is a meter properly designed to handle overload conditions. For the Amp and milliamp functions, Fluke meters incorporate a specifically designed and tested fuse that is effective to 1000 Volts as the full breaking capacity of the system which limits the energy in a manner that is as effective as a fuse located within a test probe.
It is additionally Fluke's position that a fused test probe is potentially more hazardous when used with any DMM or MFT for the following reason. It is estimated that over 90% of most electrician measurements use the AC VOLTS functions of a meter. Current measurements are generally less than 10%. If the fuse in the test probe is damaged and not noticed or properly corrected, then false voltage measurements will occur which potentially create a shock hazard for the user. [/FONT]
[FONT=&quot]For Fluke meters, a damaged fuse within the amps function of the meter does not affect voltage measurements, so the potential of shock hazard due to false readings is eliminated. Note that for the other meter functions such as ohms, Fluke meters are designed to prevent hazard for overload conditions equivalent to the maximum AC volts input as stated on the meter. These functions limit the energy by impedance. This opinion on fused test leads is limited to, and only applies to their use when used with Fluke brand test instruments."[/FONT]
