Review: Really easy to fit. Great product. - I fitted this to sub-meter my business workshop, which is supplied from the house consumer unit. I housed it in the workshop CU - a really easy fit as this unit has a good quality locking slider for the DIN rail. Just remember you will ideally want to position next to the main switch/rcd and alter the live busbar such that all the breakers are fed from the live out out of this unit.
Review: Easy to install - Spot on works as described by seller

### ⭐⭐⭐⭐⭐ Really easy to fit. Great product.

I fitted this to sub-meter my business workshop, which is supplied from the house consumer unit.

### ⭐⭐⭐⭐⭐ Fits consumer unit but cut back the live conductor lugs.
*by S***. on 25 October 2021*

These units are easy to fit and give a good indication of the KWh consumed through them. They fit on the DIN rail but will require the live conductor lugs cutting off. The units have cable connections in and out. They are rated to 45amps, I’m using them in supplies rated to 40amps.
