Hi all,
Customer is buying a Tesla ev and he was thinking of getting a Tesla charger but he said to give him 1 quote without a charger (him buying Tesla charger) and 1 quote with me supplying a charger…
The Tesla charger hasn’t got pen fault detection and I’ll need to fit one. The existing CU is split RCD and there is also no SPD or DP isolator.
My plan is to snip the tails from the meter to the split Rcd board and fit a DP isolator with SPD to provide isolation as well as upfront SPD for both EV pen unit and the existing RCD board. From the DP ISO SPD unit take tails to Henley blocks and pick up the split board with its tails. This part is where I’m a little bit stuck…
The pen fault detection device has a 2 module RCBO as the “main switch”. Let’s say the main supply fuse was 100a (couldn’t see markings British Gas tape stuck over it… the tails were 25mm). From the Henley’s do the tails to the RCBO need to be 25mm to be protected by the main 100a fuse? Feels overkill if I’m being honest just to supply a 40a RCBO. I was wondering if I can get away with 6mm tails but then it won’t be protected by the main fuse but I can’t imagine it drawing more than it needs to? What’s your thoughts?
