Yeh, it simulates the values: -  25, 5, 1, 0.5Ω Which I think is fairly representative of various types of installations.

Hi, That was the prime reason for designing this unit. It has no effect on the circuit it is pluged into. It will not trip the instalation. It emulates an RCD and provides the same test results (ie time and trip current) no matter where you plug in into. I use the mains supply for power...

Thank you for all your replies. Especially boltonsparky Yes, it does the DC level values. In line with new specifications. Not so sure of your suggestion at testing fuses, it is a bit of a onetime test is it not ?!😀 As for MCB testing, not sure if the overload test incurs repeat damage to the...

I think you might be misunderstanding. it is a device for "ongoing verification calibration" of your RCD tester in line with the requirements for use of instrument for test and inspection. No calibration is necessary as its a verification device that requires relative not absolute values. As...

Ethernetnet is differential pair data communications and hence isolated from all the power.  Your solution will work fine. It is very much unlikely that the camera will have configuration for DHCP so do not switch off any DHCP.

What has probably happened is one of your shortcuts on the browser or an application that is accessing the web for updates ect has the setting https:// as opposed to http://. Note the missing "s". The program or shortcut is trying to open a site with the secure "s" whilst the site does not...
