What is the minimum load in watts for a 300 watt 120 volt to 12 volt 300 watt underground transformer to operate safely? We have always loaded the transformers to one third of capacity (300 watts = at least a 100 watt load)

Do you also manufacture sized-to-the-load de-buzzing coils? We sourced a 1200w choke, but it had minimal effect on the transformer noise in the space - the connected load is only 300w. Thank you!

Every two weeks for the last 2 years, a 12 volt incandescent lamp burns out.  Voltage at lamp is 10.8 VAC typically.  We called the fixture manufacturer and they said it was a transformer issue.  How can we eliminate lamp failure?

Six MR16, 50watt, 12volt lamps on each cable/track. I have to reset using the rocker switch (low voltage circuit breaker on the Semper Fi transformer). One track trips after about 10 to 15 minutes. The other one trips after track been on for a day. Electrician was thinking the dust build up on the track could be causing the problem.
