I wonder if grounding may have helped save the ballast! What if the ignitor had kept igniting and had no place to go since it wasn't connected to grounding and went through the coils ruining it? Electricty will find any place with least resintace to go through!
Yep I definitely agree with replacing the cord with a grounded weather proof one, I would also suggest adding a inline fuseholder or a fuse block with the properly sized fuse too.
Better use weatherproof.....the UV from the sun can damage the non weatherproof cords.....even wires used in EMT outdoors are usually using UF wires....I will look up the code book and let you know what you need....
EMT outdoors? I don't have my Canadian Electrical Code with me, but I think EMT isn't permitted outdoor, it's either rigid or PVC. I'm not sure though.
Yes that is correct.....the liquidtight flex is the grey pipe right??? What kind of connectors and complings do the liquidtight flex use? And how would one connect with a plug and a timer? Perhaps have a juction box and a outlet inside the juction box (juction box being big enough to fit timer iniside???)
Well I know that most XLPE-insulated wires (like XHHN and XHWN) can't be used when exposed to sunlight, since they're made of cross-linked polyethylene. And the THHN isn't allowed either anyway.
The THWN is PVC-based, so it necessarily acts differently under sunlight. I don't remember if it's permitted under these conditions though, but I think it is.
The RWU-90 is probably the best for outdoor applications. There also exists the the RW-90, with the only difference being not to be permitted underground.
Jace, the liquid-tight is a flexible metallic conduit with a layer of flexible rubber over it. It uses special connectors that I did use back before Xmas. Once assembled, the whole connectors/conduit thing is 100% liquid tight. However I think the Canadian code won't allow runs of liquid-tight longer than 1,5m (~ 4,5ft), with some exceptions.
