Overview

The Metrel Installation Tester is designed for compliance testing to the AS/NZ3000 standard. This multifunctional device is suitable for testing appliances and installations, combining the capabilities of 12 instruments into one highly specified tester. Specifically built to meet Australian standards, it provides the ultimate all-in-one testing solution.

Clever accessories, such as the optional 3-phase adaptor kit, allow for easy deployment of the tester in various environments. An optional resistor box (not included) can be connected to the switchboard during installation testing, eliminating the need for lengthy trailing earth leads during outlet socket testing. Built-in thresholds deliver clear results with PASS/FAIL indications in accordance with AS3000 specifications, similar to an appliance tester.

Decent install power strip
Style: 20W_USB-C, Size: 6FT
I really like this search strip as I installed the inside of my RV the only problem I have with it is if you were using bulky transformer style plugs like that of a iMac laptop, charger or other big transformers, you will not be able to use the USB outlets in the center and I don’t know if that’s by design to limit current flow, but it sucks.

An absolute must for countertops used as workstations.
Style: 20W_USB-C, Size: 6FT
These were the best thing I did when we had to remodel and I added a large built in countertop. They are made well, and easy to install! They are very versatile since they are designed with both USB-A and USB-C ports along with the standard 110V plugs. I use these with my 3-D printers, laser engravers, computers, printers, and even a few coffee pots!

No issues, and no instructions.
Style: 20W_USB-C, Size: 6FT
No, you don’t need instructions, because the hole dimensions are in one of the photos. 4” x 1.73” is perfect. Plug it in and all of the ports in both that we bought worked perfectly.
