Solar system postponed

Featured Replies

 

Engaging a Bangkok-based electrical firm/contractor for the design and installation of the electrical system in my new house unfortunately didn’t work out, as Buri Ram seems to be too far for them to service. It’s a pity, since I was hoping they could handle part of the solar installation as well as install surge protection devices (SPD) to mitigate brief voltage spikes.

For now, I will likely rely on a local village electrician who has experience with basic household wiring but little to no knowledge of solar systems. Fingers crossed that all goes smoothly. Given this, I’ve decided to postpone installing the solar setup, surge protection, and related equipment until I can find someone qualified to handle the conversion in the future.

At present, I’m in the process of putting together a kind of “bill of materials” for the electrical system. As I prefer to use sheathed wiring, I’d appreciate confirmation - or pointers - regarding appropriate wire sizes (in sqmm) and their corresponding breaker ratings in the consumer unit.

  • Ceiling lights: 1.5 sqmm
  • Electrical sockets, air-condition units and water pump: 2.5 sqmm
  • Water heaters: 6 sqmm    

I’m unsure, however, about the correct size for the ground wire, including the main ground wire from the consumer unit to the copper earth stake and the best type of consumer unit. Lastly, am I correct in assuming that the water pump, air-conditioning units, and water heaters should each be protected by individual breakers?

I've seen this company in Buri Ram, opposite the DoHome, that supplies and installs solar systems, but have no info about how good they are.  When I get around to converting our place to solar I'll check them out.

Earth wire needs to be sized to carry the fault current but only for a very brief instant until the ELCB trips. I used 10mm² for mine.

Big power stuff tends to each have their own breaker and also a local isolator near the device.

 

Where are you in Buriram?

Maybe I can help with the solar.

My place is near the Bird Sanctuary (Suan Nok)

Must be a relative new outfit - good to know, thanks.

You might try to find an electrician who is a retired Navy (Thai Navy or otherwise) electrician. Ship-board systems involve DC wiring and AC/DC conversion that is very similar to solar system usage.
