There was a steel factory across the road from where I work which had a DC service in use up until they moved and the building was demolished 12 months ago. They also had a 200V 3 phase service. The DC was used for the overhead craines and some machines. Aparently the DC cable was of epic proportions and much fun was had weighing it in!

I took my time, I hurried up, The choice was mine, I didn't think enough
