Like C-H, I would tend to agree with Lyledunn.
Please also bear in mind that HV training is an on-going thing, as in once you have a certain qualification in HV work, the need to keep your knowledge of new techniques and safety requirements is a constant thing.
Don't get me wrong, there are a few people here at ECN that are experienced in HV and EHV work and really enjoy it and I am most certainly not trying to put you off getting into this sort of work, I prefer it to house re-wires and so forth.
Only competent persons work on MV/HV/EHV systems, this sort of work is never bodged, so you don't usually have unusual wiring practices and so forth.
I'd say get into it!!. [Linked Image]
