decent priced rcbo, wylex always great quality simple to fit
Replaced MCB for solar system to overcome loss of power to other circuits, and provide earth leakage and overload protection for solar.
Good quality RCBO, screw terminals are a decent size for tightening and the cable clamps are well made. My go to brand for board changes.
Good product. Same size as an MCB.
However it isn't compatible with the older Wylex MCBs and consumer units which use a different bus-bar. It only fits onto the pronged bus bars and not the slotted ones.
Found it easy on the site. Did not have in stock at local branch but was dispatched and received quickly
Thankyou. Having cancer we needed the shower up and running again as we did not realise when we upgraded the trip was not big enough.
Rather expensive compare to other RCBO's but the only one of its type available for an EV commando socket. The first one supplied failed the electricians tripping current test Toolstation replaced it without a quibble and that was OK.
This is a combined circuit breaker and RCD. The A type in the description relates to the type of RCD not the type of circuit breaker.
The description is not wrong as stated by previous reviewer, proving that electrical work should be left to qualified professionals not amateur DIYers
