The concept is good, but potential dangerous as LIVE voltage is easily accessible through two of the banana sockets.

Suggest modifications (built-in lamp and a.c. voltmeter, or alternatively, use sheathed banana socket/plug sets) as suggested by eRIK.

Other minor modifications:
1) incorporate a separate siwitch to isolate line voltages from the connections.
2) incorporate a switch to toggle between the built-in lamp or a short along the LIVE line (this saves the hassle of manually inserting the lamp or the short-circuit plugs)

Overall, these modifications will minimise the risk of electrical shocks.

HI,
You might look at a product called Kill-a-Watt I plug it into my vari-ac adjustable transformer you should use the isolated version,
It reads out on a digital scale volts,amps,watts,and Hz and it inexpensive!
Have fun!

Hi Mike,

Many thanks for your comment, I totally agree. There are now interesting devices to check how much electricity you are using. Here is one:

In reply to eRIK.

Hi Erik,

Thanks for your comment and suggestions.

Yes an inbuilt ampere meter and voltmeter would be the ideal solution. Mine is still the cheap version 🙂 But as I am the only one operating it I am very careful. This is also the reason why I am using a transparent mains plug with the light inside so I can see when it is powered from the mains. The plastic box is normally closed so no one can touch the life parts. But yes, shrink wrapping them is the way to be even safer. I will do that too.

I will anyway put a separate switch that insulates the whole box. Probably this weekend... We are never too careful.

Cheers,
GM
