There's no such thing as a water-tight seal. Drill holes on the low-points of your conduit for water to evacuate. This will help with regular weather changes like condensation and pressure changes. You're not waterproof if you don't evacuate water. Brilliant video!
@peterg.82454 жыл бұрын
Better yet install a piece of rigid conduit with a T box and at least a filter drain to keep out the critters. When I worked the petrochemical industry we couldn’t allow pooling, because it might be explosive so no flex except for the last 18” and a T and a drain on every low point. The box needs a drain too since condensation will fill to the level of your bushing.

Absolutely not! It may sound like a good idea, but you're creating a weak point on the wire that's subject to breaking if/when it flexes. Additionally, you're filling the terminal with a metal that softens and melts at a very low temperature (ie if the connection starts to heat up for whatever reason). A proper crimp is superior to solder in this application.

I've seen a lot of rookie engineer's making the most stupid mistakes working around boxes like this, the worst is that they open a "company" offering their services very very cheap! That has cost us, the professionals in this field the loss of revenue, but, many times they call us back to fix the stupidities done by the rookies! 40 years of experience you don't get it even if you go to the most prestigious universities or technical garage schools. Electricity is deadly in many ways, either DC or AC. I never take short cuts, I know about many people being killed because a simple mistake. Take it seriously! Electricity can kill!
