The photo is from an overenthusiastic tourist who have dozens of photos from his trip to Tuvalu on his website.

I don't expect anyone to recognize the particular transformers, I only wanted to know country of origin. Does the warning signs give a lead? They don't tell me as a Swede anything, but I thought you who live in English-speaking countries might recognize them.

The reason is that the sockets are reported as Australian, the system as the British/Australian 240/415V and the history book tells it was a British colony. But, the frequency is reported by some sources as the American 60Hz... It can happen - a small number of countries have "mixed" systems like this, but it is rare. In most cases it indicates an error in the information. I'm gonna be an expert in colonial history soon [Linked Image]

I know I'm pedantic, but the gaps and errors in the list annoy me.

I'm writing a full explanation of everything in the database, a FAQ and a description of the different electrical systems. Only trouble is that it takes some time.
