Answer: 
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

Answer: 
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.

Answer: 
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?

This question is from 20-Amp Power Inlet Box,
Asked by
USA
Read all my Q&A
May 7, 2016
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?

Answer: 
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 Read More

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). Read Less

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.
