Product Overview

The LIVE Electrical RKB140C-030 Type B RCBO is a high-capacity, single-module residual current breaker with overcurrent protection, designed to provide advanced circuit safety in demanding modern electrical installations. It offers comprehensive protection against overload currents, short circuits and earth leakage faults, while supporting systems that generate complex electrical waveforms.

This Type B RCBO is engineered to detect AC, pulsating DC and smooth DC residual currents, ensuring reliable protection where conventional RCBOs may be unsuitable. Its bi-directional power flow capability makes it particularly well suited to renewable energy systems and installations incorporating power electronics.

Featuring a C-curve tripping characteristic, the RKB140C-030 is ideal for circuits with higher inrush currents such as EV charging equipment, solar PV inverters and heat pumps. Rated at 40A, with a 30mA residual current sensitivity and a 6kA breaking capacity, it delivers robust, standards-compliant circuit protection.

Nice to Have 90° Angle USB-C Adapters
The Herfair 180 Degree USB C Adapter is compact, simple to use, and fits snugly inside the USB C ports I've plugged it into. I got it to use with my Steam Deck, since the charging port comes out of the top of the device, and holding it with the cord sticking out of the top creates unneeded pressure. Something like the Nintendo Switch has the port coming out of the bottom, but then you can't comfortably rest the device in your lap. The benefit of using this adapter is that I'm now getting the best of both worlds. It extends just enough to let the cord freely travel down the back of the Deck, but it's compact enough that I can set the Deck down on a flat surface and the adapter doesn't touch the desk or tabletop. Even better, it fits right alongside the exhaust fan attachment that I use to keep the Deck cool. All in all, this adapter did exactly what I was hoping it would and fits so well that I can pretty much forget it's there unless I'm putting the Deck in its carrying case. I'm really glad to have this!

Does exactly what you need it for.
I like these adapters. Some pros: * There's a blue light to show that power is coming to the adapter (great to ensure you've plugged it in correctly) * The gap at the bottom of the plug ensures that it works with a phone in a case. (I tested it on an iPhone 15 pro max) * The connectors are solid good click when connected. * The housing is solid aluminum (no flex or seams, etc) * There is a little label on each that shows how much power or data can go through it. Use case: * Allowing you to use your phone on your bed while the phone is sitting on your chest (and still plugged in) * For the USB-C to female USB-A female adapter, the page shows that you can use this to connect a flash drive or a regular USB-A cable with the other end going to your peripheral (like a keyboard or game controller) Overall, this is a great item to own in your gadget bag.

They work.
They work fine for my sort of "specialized?" use. By relieving the strain on the laptops USB ports. Hopefully, prolonging their lifespan. Do wish they would make the edges and corners a bit rounded.

I can use my remote again
Style: 1 to 1 IR Repeater
I added a center channel speaker, and it was partially blocking the remote sensor. This solution works like a charm and has an easy setup. One end points towards the existing IR, and the other end goes where you are going to point the remote to. The only suggestion is to include a USB connector with the product, so I don't need to find one.
