Prior to having solar panels fitted my consumer unit arrangement was as follows:
1. Main isolator
2 .RCBO for garden power
3. RCBO for lighting
4. RCBO for freezer circuit
5. Main RCD for remainder
6. Ring final 1
7. Ring final 2
8. Immersion heater
9. Shower
10. Spare
Now the electrician who wired the solar panels shifted the bus bars to leave 5 breakers to the left of the main RCD to free up the spare socket for the solar input (without RCD), but this also removed the RCD protection from the immersion heater. He told me that the immersion heater did not need an RCD. I am concerned about this, any comments would be appreciated. I could move the immersion heater to an RCD protected position as the electric shower has been replaced with a power shower off the ring final.
