Evening all,
I am a newbie to this site and also to electrical work. I am currently a young road lighting technician at the local council and am studying for a HNC in electrical engineering, a G39 and a Diploma in road lighting standards. I have been in contact with a consultant and he has brought up a question that my little-to-no practical knowledge of electrical installations.
Currently we have a distribution pillar that feeds adjacent Lighting column with a 10A BS88 fuse, and is then sub-fused in the control column with a 6A BS88. The power consumption is 60W from the lamp. The cable size going into the column is 2.5mm PVC cable. TN-C-S supply.
I have spoke to my tutor and he recommends that if the 6A Fuse would have enough discrimination if if was a fast blow fuse. But I cannot find anything on the fuses that indicate what type it is.
If anyone could help me or point me in the right direction, that would be appreciated.
e.g. What formulae should I use to be working this out?
Also if there is any more information needed to make this more clear. I will be happy to assist.
