The 10 amp (non fused) connection on your multimeter is for measuring DC amperage over a short time span 10-15 sec's max , never for AC amperage, for that you need a clamp meter.


As for needing an electrician it's like needing a trained pilot in a plane , follow the instructions and have 2-3 hrs on a simulator and away you go , electrical work is covered by laws and legal requirements to protect not only you but anyone who comes after you in an attempt to stop as many as possible deaths by electrution , end of story.
If in doubt ask your local authority if you are or are not allowed to carry out said work or do you need a licenced person?

Hey ashore, can you explain why ?
I am puzzled by your assertion about the DC only ?

As for the 10A non fused inputs, where did you get such a device ?
I don't think I've ever seen a non fused current input on a multimeter.

You will notice in the specs/manual of your multimeter is has a mention about continuous and peak reading with time limits. That is what you should refer too, your multimeter might only be able to hold the 10A reading for 5 seconds ...

Why I said not to test AC current was because a lot of multi meters will only play nicely with ac current under 20milliamps and in answering metal heads question the meters I have used that had a 10amp unfused socket were for DC only , I have not bought any good meters for the last 10 years as my old ones are all working and are more than I need, there may be new thecnology in the latest meters that allows you to test high range AC current if there is I haven't seen it , so rather than offer an opinion or give advice that may cause someone to damage their meter I went on the safety side in saying only use a clamp meter to measure AC Current .:D

Picture below of two meters both with non fused 10Amp DC current input sockets .

You are of course correct you should always read the specs , trouble is very few do until all else fails , and even then may find them hard to understand . My saying 10-15 secs max was from the lower limit of my meters and I should not have generalized as 15 secs may indeed damage a diffrent meter,

Makes sense now

You can say that again:2tsup:
