I have 25 metal halide lamps- 150 watt each with electronic ballast- a 10 amp MCB - but after two years this is tripping - these lamps are all on one circuit - what could be the cause and how to fix?

You have a total of 3750 watts on the circuit. The circuit amperage needs to be found but no voltage was stated. Use the following equation to find the amperage, I = W/E, Amps = Watts/Volts. Once the amperage is established then troubleshooting can commence. If the amperage is close to the threshold of the breaker then that might be a problem. One of the ballasts could be going to ground and drawing more current than the circuit breaker will allow. First find the circuit's amperage.

Can you use a 400W high pressure sodium bulb in a metal halide ballast?
No, the ballast has to be matched to the lamp. 250 watt ballast, 250 watt lamp. Also be sure to match the lamp type to the proper ballast even though the wattage is the same. HPS ballast to HPS lamp, Metal halide ballast to metal halide lamp and mercury vapour lamp to mercury vapour ballast.
Can you use 250W metal halide bulb in a 1000W metal halide ballast?
No. The lamp has to match the ballast. The lamp will not ignite if the wrong ballast is used.
How do you ignite a 400w electronic metal halide or high pressure sodium bulb?
You need the appropriate ballast for either of these bulbs to make them light.
Does a metal halide and mercury vapor use the same ballast?
No. A mercury vapor lamp will work on a metal halide ballast, but not the other way around.
Can you run a 50 watt halide bulb on a 100 watt halide ballast?
Yes.
Can you use a 70 watt metal halide lamp in a 150 watt ballast?
Yes assuming the ballast is also for a metal halide lamp.
Will a hps luminaire run a metal halide lamp?
Yes the ballast and starter are the same you can run halide in hps, but not hps in halide.
How does a metal halide ballast work?
A metal halide ballast works just by transforming the line voltage into much more useful voltage to the metal halide, and by regulating the current so that the bulb will have its useful life at the most.
Why Metal halide fixture with a 175 w bulb and correct ballast could overheat?
Make sure you are using a metal halide bulb and the ballast is matched to the wattage on the bulb. These both must be correct.
What size wire and breaker you need for metal halide 400w bulb?
The size of wire and breaker sizing are based on the current of the circuit. To answer this question a voltage must be stated or look on the ballast for the amperage and add that to the question.
What is the formula for calculating the full current load of a 400 watt metal halide light?
For the amperage of a metal halide fixture look for the nameplate which can be found on the side of the ballast. There it will tell you what the amperage of the fixture draws. Knowing what one fixture draws will allow you to size the lighting circuit for wire and breaker sizes.
Can a 400 watt high pressure sodium bulb be used in a 400 watt metal halide ballast?
I actually have a 400w hps ballast and I can also use my 400w metal halide bulb in it with no problem. So what your saying is they do, but they dont? the answer is, they dont. You can get universal bulbs hps to plug into a mh ballast they have a miniturized igniter inside the bulb. As I understand it, a 400W metal halide bulb can be used with a 400W hps ballast, but not the converse. A MH bulb has the igniter in the bulb, and the HPS has it in the ballast--which pretty much goes along with your comment above. Apparently the double presence of the igniter in the HPS setup is OK.you can run metal halide in same wattage's but not hps in metal halide systems.you can run such as (same wattage's)250 watt metal halide-400 watt halide ect in hps systems but not hps bulbs in halide systems. they make conversion bulbs to run halide in hps as well and vice versa.
