  4 Questions
Q: Will this PB30 work to connect the L14-30 cord with 8 gauge wire feeding the transfer switch?
by Marian from Michigan on December 15, 2013

A: Model PB30 has a L14-30R receptacle to match a L14-30P Plug/Cord. The wire sizing range for the inlet box is AWG #10 minimum, AWG #8 maximum.

Q: Does this product provide a rain tight connection when product is in use? This is a current requirement of the National Electrical Code.

It does not look like it fills the in use portion of the code.


by John Moisuk from Connecticut on October 03, 2013

A: Thank you for your interest in Electric Generators Direct.

The Reliance Controls, PB30 power inlet box is rated as a NEMA 3R enclosure and will be suitable as an outdoor connection.

The NEC standard you are referring to covers outdoor, “live” receptacles which is why you will notice that many outdoor receptacles feature gasket material. In the case of a power inlet box, the device itself is not considered live until hooked up to a generator and the transfer mechanism switched. Under any other circumstances, the outlet would not be live as there should be no closed circuits leading to it.

For an added degree of protection, we could recommend one of the "rain tight" power inlet boxes. These will feature the connection point on the bottom of the enclosure to further minimize the risk of water infiltration.

Our recommendation would be the PBN30.

Q: Is the Reliance Q310C a good choice for my Generac XP7000E. My electrician indicates a need for a 20A 2pole and a 15A 2 pole as well as several single pole breakers. Are the replaceable breakers similar to the Murray that are so available.
Is the Reliance PB30 inlet box a good choice?

by Allan Peck from Massachusetts on May 24, 2012

A: You cannot use the Q310C with the Generac XP generators. The control panel on the XP models is GFI protected so you must use a GFI type transfer switch. The Reliance Controls "X Series" switches are recommended. Here are a couple models and they are very versatile....

30A GFI Transfer Panels

The PB30 inlet box is a good choice.

Reliance controls is a well known brand in the generator industry. This product earns the better award because of it's compact design and light weight.

You can't beat it.

Power, Yes!!!!!
After being without power for 5 days through last year's storm (Sandy) my wife "politely" asked me to buy a generator. I thought it was a great idea, of course. Seriously, it gave us piece of mind knowing that we have a generator should we lose power again. I did my research and decided to go via electric generators direct and was happy with the service, delivery and any follow-up questions I had. TY. Now I won't need to sleep on the couch...lol

Horrible Piece Of Equipment
Just to hook up the case ground was a struggle using #10 wire, not enough room for bending wire once in connector holes. I'm really surprised this got a UL seal of approval on it. It would be much better if it came pre-wired to terminal blocks and run wire straight into it

Very Adequate
Needed a inlet box to power my hunting cabin. No commercial electric service so I use a 3500 watt generator. The Reliance Mod. PB30 was the correct entrance box for my use. Very easy to work with and have experienced zero problems since the installation of the box. Highly recommend.
Pros: Durable, Easy To Use, Reliable, Price

Excellent Choice
My Second review!!!

So far I would say it's still a EXCELLENT CHOICE; we ran the generator for 35 hours with no problem. It ran the whole house after the Sandy Storm and also helped a neighbor.


*****Most Important- 5 gallon of gas got me 13 hours on a half load.*******

First Review!!!!!

I recently picked up a Generac XG8000E, a 30 amp CableMaster (4 prong), and a Reliance Controls 30-Amp (4-Prong) Power Inlet Box and had my home set up by an electrician. He used an interlock... more

Prepared This Time
We were without power for a week after the ice storm in Southern Michigan in February of 2010. Miserable. Had to use kerosene heater to heat some of the house (sort of). Lost the food we had in the freezer and the refrigerator. Thank goodness we are on city water with a gas water heater so at least we had water. I decided we weren't going through that again, so I bought a 7,000 watt generator, power outlet, and transfer switch.

I was concerned about installing the transfer switch... more
