Truu - really good thread, you've definitely caught my attention. If i could make a suggestion, re electrical failures with those inexpensive digital timers. I've used intermatic mechanical timers that are contained in their own little metal cabinets on furnaces etc.
for the grow "room" i'm building i had a little intermatic digital timer, model DT620CL that i'd bought few years back (love the battery backup so i don't loose the timer schedule if power goes out). Decided to use two timers so went to buy another of the same, and found intermatic now offers both the original model and a newer model, the DT620, basically for a few bucks cheaper (earlier one had a lifetime warranty). The part i think folks might want to think about, i noticed one of the reviews on the newer model, the owner indicated it had apparently failed and was in the process of starting a fire (owner was nearby and smelled the plastic burning). For the heck of it, i mentioned that to a bud that i knew was using a similiar digital timer and kind of flipped out when he said his had already melted down. The amazon reviewer said he was running 250W draw with "Tungsten" lighting (i have no idea if that influenced the event as i'm fairly electric illiterate), but my bud runs about 600 watts of incandescent lighting off his. Those timers, both the earlier version & the newer one, are 15 amp rated so they should have handled considerably more with ease . I don't believe in coincidences and learning about two failures that could have resulted in fires, in the same week bothered me and got me wondering how common an issue it is.
I'm sure the surge strip would shut down at some point, but have to wonder if it'd shut down before the unit was dripping burning plastic. I only mentioned the brand (intermatic) as it's a long established mfgr and i had assumed they'd be decent quality vs the chinese copies (even though they're all probably made in china).
As i'd already bought the second DT620CL, i didn't want to throw them away, so i basically copied what intermatic had done with the mechanical units i've used, and modified some metal boxes (an old first aid kit and a military ammo box) to keep the units in, so that in the event of it sparking / melting down, no burning plastic can drip on flammable material etc. Just so i sleep better.
old circuit breaker panel boxes would really be ideal for the same purpose though
anyway, fwiw
again, great thread - I'm definitley following it
