## Specifications

### Identity and connection
- Brand: Nilight
- Model: 50452RV
- Connector listed in title and product details: NEMA L5-30P
- Rated voltage and current: Rated for 30AMP 125V
- Advertised maximum load: Rated for 30A 125V, 3750W.
### Construction and installation
- Material: Metal
- Finish: Powder Coated
- Installation type: Screw-In
- Enclosure entry points: There are 4 pre-drilled holes on the box, no need to drill holes

## Before you buy

- The listing is inconsistent about the connector: the title and main details specify three-prong NEMA L5-30P at 125V, while an A+ panel describes four-prong NEMA L14-30P at 125/250V and 7500W. Confirm the selected unit's plug type and rating before matching it to a generator cord or wiring system. The outdoor and ETL statements are listing claims, not independently verified here.

## In the box

- 30 AMP Generator Power Inlet Box (Included)
- 3 mounting screws (Check selected pack): Mentioned in a feature description, but absent from the explicit included-components field.
- Installation guidance (Check selected pack): Mentioned in a feature description, but absent from the explicit included-components field.

## A good fit for

- Generator backup wiring that requires a 30A, 125V NEMA L5-30P inlet, once the exact selected configuration is confirmed.
- Installers who want pre-drilled cable-entry openings and a visible connection indicator.

## Less suited to

- Buyers whose setup requires a four-prong NEMA L14-30P, 125/250V inlet unless the selected configuration is confirmed to match.
- Anyone seeking a plug-and-play solution without electrical installation.

## Customer feedback

Customer feedback describes the inlet box as working well and easy to install. That feedback may matter to buyers looking for a straightforward installation, but it does not resolve the listing's conflicting L5-30P and L14-30P specifications. Aggregate ratings are generally favorable, with some lower ratings also present, and do not establish why customers rated it that way.
- Positive themes: Customers describe the box as working well.
- Positive themes: Customers describe installation as easy.

## Frequently asked questions

### What connector does the Nilight 50452RV use?
The title and main listing details say NEMA L5-30P, but an A+ panel describes NEMA L14-30P. Verify the connector on the selected listing before purchase.
### What electrical rating is listed?
The main product details state 30AMP at 125V. An A+ panel separately claims 30A at 125/250V and 7500W for the L14-30P version, so do not assume those specifications apply to the titled configuration.
### Does the inlet box have pre-drilled cable entries?
Yes. The listing describes four pre-drilled openings around the enclosure.
### What comes with the inlet box?
The explicit included-components field lists the inlet box. A feature description additionally claims three mounting screws and installation guidance, so check the selected listing for those items.
