Fused Connection Units.

Zoomup

As I sit here ruminating (yes madam it is legal in Norfolk), I recall the switched fused connection units of old. I have installed a few in my time for gas boiler supplies etc.

I was fond of a certain make at the time in the early days, which had the two incoming supply terminals next to each other, L & N that is. I seem to recall that they were mounted at the top of the accessory. The outgoing terminals were dotted about elsewhere and I had to read the markings to identify them.

Nowaydays the terminals are positioned every which way as the Americans say. So care is needed to connect the accessories correctly.

Which is your preferred make/design of switched fused connection unit?

Edit. Add. A re-invention of the wheel here with this design. I feel young again.

    Depends on the environment, heated locations or restricted airflow, or long cable scrabbling for voltage drop might see 2.5mm. But generally yes 1,5mm or less ought to be fine in most places.

     

    I'd agree there seems to be a very wide variation in where the terminals are, and that means that the cable previously dressed for another maker's offering is not always a good fit to the replacement.
