Just collected a B40 by Hager. Acc to the shop, this make requires an exceptionally high torque compared to other makes. It's 3.2 Nm ! So that's what it'll get, as soon as I can get a Draper torque s'driver delivered. Just have to be d*mn tight for a couple of days...I use a torque screwdriver for all final terminations, 2.5nt.
Vehicle converts AC to DC to charge the vehicle. DC creep leakages can occur to ground, and silently kill the TypeA RCDHis is AC.
Probably, but it is still a good idea to switch over to the TypeB for maximum protection. If you have a neighbor with solar panels installed, even their DC leakage can wreak havoc on TypeA RCDsThere's a 40A RCBO inside the EVSE unit downstream from this mini CU box; will that do the job?
Yikes! neighbour? What about my own panels ??? Ok, I'll get me a type B 40.... but it is still a good idea to switch over to the TypeB for maximum protection. If you have a neighbor with solar panels installed, even their DC leakage can wreak havoc on TypeA RCDs
And now we enter a world of confusion because someone, somewhere didn't think when they allocated letters to types ...Yikes! neighbour? What about my own panels ??? Ok, I'll get me a type B 40.
But, should I have an RCD, or RCBO? Google suggests RCBO = RDC + Switch; presumably the MCB I have is already that switch, so just a plain 'old B40 RCD is what I should have? So much to learn, just as I thought it was all settled ...
I noticed that too. It might explain why they seem to be so wide and expensive as the single phase ones are probably just altered 3ph (until demand is enough to produce a line of smaller ones).Type B RCD are intended to be used for loads with three-phase rectifier, such as variable speed drives, PV system, EV charging station and medical equipment.
