I bought my condo in Chiang Mai many years ago and had all the internal wiring replaced and chased into the walls. I had a new consumer unit fitted above the door.

I didn't check, which is unlike me, what size/rating of cable was installed. I am assuming a higher rated cable for the electric shower. I did have a "4 foot" copper rod placed in the ground outside, I am on the 2nd floor (Thai), so it's not far to get to the ground outside.

I've seen recently two new cable trunks from recently renovated condos going along the corridor ceiling to the electrical cupboard by the stairs where the main breakers and meters are.

I have been running 2 induction stoves, sometimes whilst boiling a kettle but I know if I were to use my toaster oven the breaker would trip in the cupboard but not my consumer unit. It happened a couple of times in the past so I know now not to have 4 appliances on simultaneously.

If I buy an oven rated at either 2300W or 3250W, the two I am looking at, I assume it will need to have a new dedicated circuit installed. It will have to be surface mounted.

Is there a standard supply rating for condos? From what I can tell this condo was built around 1970 when people had a lot fewer electrical appliances.

Do I need to contact PEA first? Am I likely to need a new circuit from the meter?

What size is the breaker you're tripping? You have your own meter, yes?

If you are already popping the breaker supplying your consumer unit, a dedicated circuit from the CU to the oven likely will not help.

You may want to bite the bullet and increase the service to your CU.

Do you get your bills direct from PEA or via the condo?

As above, what value is the breaker you're popping (a photo would be handy).
