Asked by: Rich
Most of the local HD stores in my area only stock the 30A (Reliance PB-30) model. The 20A (PB-20) I had to get from HomeDepot.com

Is this unit weather proof while in use or only when closed?

Description says water tight but cover does not close over the plug while in use like most outdoor weather proof boxes.
Asked by: KC
Water will not get in even when the cover is open and a connector is inserted. This inlet box does not have a cover that closes over the connector because those "while in use" requirements apply only to power outlets, not to inlets like this one.

I am searching for a male plug to mount to the outside of a cargo trailer to plug and extension cord into to power a charger/maintainer.
Asked by: George
This product is a power inlet box intended to connect a portable generator to household wiring. It is probably not appropriate for your application.

Can it handle 30A? Is that legal?

I want to put in 30 amp wiring ready to use either a 20 or 30 amp generator. I can find a twist-lock adapter to hook a 30 amp generator to a 20 amp connection, always in stock along with the cords by the generators, but I don't see an adapter for hooking a 20 amp generator to a 30 amp house connection. That would seem to imply that I need to install a smaller inlet like this, if it can legally handle 30 amps, and use the 30-amp-source-to-20-amp-sink adapter. What's the best way to go?
Asked by: outbacker
Do not connect a 30 amp generator to a cord or inlet box rated for 20 amps. For an installation that can use any generator up to 30 amps, install a 30 amp power inlet box (Reliance Controls model PB30, internet no. 202213702) and 10 AWG wire. To connect a 20 amp generator to the 30 amp inlet box there are a couple options. First, many 20 amp generators have a four conductor outlet rated at 30 amps. In this case all you need is a standard 30 amp cord. If the four conductor outlet on the generator is 20 amps there are two options: 1. Use a 20 amp cord and replace the connector on the inlet box end with a 30 amp connector that matches the inlet box (internet no. 202216503), or 2. Use a 30 amp cord and replace the plug on the generator end with a 20 amp connector that matches the generator (internet no. 202216502).

Rated 5 out of 5 by from Excellent Quality This is a very nice power inlet box. It is fairly small in comparison to some that I have installed and is of a higher quality. It makes for a nice clean looking installation for connecting your generator cable. I just wish they would bring the price down...

Rated 5 out of 5 by from Exactly what I was looking for! The area I live in, the electricity goes out WAY to much. Connecting these inlet boxes to my main electric box and outside makes things alot easier when I have to use my generator.
