    Weather resistant plug

    I seen awhile back but cannot find a post showing where someone had used "liquidtight" conduit and a twist lock 240V plug. Can anyone point me in the right direction as to how this can be accomplished? I am going to install a 240V outlet for my pool pump motor and want to encase the wiring in liquidtight conduit. I am having a hard time time an adapter that allows the liquidtight to connect to the plug head. I will have the outlet in an outdoor weather resistant box but want the conduit to be fully sealed. Any help would be greatly appreciated.

    Re: Weather resistant plug

    So that male plug (your link is for a 4 pin instead of a 3 pin) accepts the liquidtight conduit? Thats the part I am unsure of. I understand the rest and thanks for the links just to verify I am on the correct path.

    Re: Weather resistant plug

    Oh, gotcha. No, the twistlock plug does not accept liquid tight and the plug not weather tight. The weatherproof, in use outlet cover is what makes that end weather tight.

    You'll need a big one like this, Shop Hubbell TayMac 1-Gang Rectangle Plastic Weatherproof Electrical Box Cover at Lowes.com

    Re: Weather resistant plug

    That is the box I was looking to use. So will the liquid tight just but against the plug? I may try to figure something out at the store to at least make a decent seal. Maybe not water tight (the cover will accomplish that) but something more than liquid tight just being cut flush against the plug.

    Usually the box is sealed. You can use silicon around the plug to seal between sealtight and butt end of plug if you think needed

    Re: Weather resistant plug

    Ok, I'm slowly getting the picture here. Is it Monday?

    Don't use liquidtight at the pump. Use something like this, Shop Gampak 1-in NM/SE Connector at Lowes.com , and an outdoor rated pre-made up cable. They will have some on the bulk wire dispenser.

    Re: Weather resistant plug

    So will the premade cable have a shielded #12 wire in the mix? That is the issue I am running into with that route.

    I believe so. I can't figure out how to see the by the foot bulk wire but it seems like i remember them having 10-3 and 12-3 wire in a black rubber outdoor rated jacket by the foot.

    Re: Weather resistant plug

    Thanks. I will check that out. As long as its all single strand and each shielded that may be the way to go. Codes / inspectors do not like seeing that bear copper wire in a strand of wire going to pool equipment.
