Question: Does it exist?Like this, but weatherproof.They want a disconnect at the well site for the single phase well pump. They are usually about 8 amps, so I plan to use a 20 or 30 amp 2 pole toggle switch, but I'm running #10 wiring out there for VD, and using 1" PVC because I like to make life easy for myself. Maybe 3/4" if I'm feeling ambitious and I can't find a 2 gang box with 1" KOs.

Yes, a weatherproof 2-pole disconnect switch in a suitable enclosure absolutely exists. You can definitely accomplish what you're aiming for. Here's a breakdown of the components and things to consider

Components You Need:
Weatherproof Enclosure

This is the key to making it safe for outdoor use. Look for NEMA 3R or NEMA 4 rated enclosures. NEMA 3R protects against rain, sleet, snow, and ice formation. NEMA 4 provides protection against hose-directed water, making it even more robust. A metal or plastic enclosure is fine, but metal provides better impact resistance. A 2-gang enclosure is perfect if you want room for an optional outlet, although not technically required.


2-Pole Toggle Switch

A 2-pole switch is exactly what you need for disconnecting both legs of a single-phase 240V circuit. Since your pump draws 8 amps, a 20-amp or 30-amp rated switch is acceptable. Oversizing slightly is fine and might even be beneficial for longevity. A toggle switch is fine, but rotary disconnect switches are also popular for this application. The switch must be rated for the voltage and current you're using (e.g., 240V, 20A or 30A).

Weatherproof Cover Plate

This covers the switch and provides additional protection against the elements. Make sure it's designed for the switch you're using and the enclosure.


Conduit Fittings

These connect your PVC conduit to the weatherproof enclosure. You'll need weatherproof conduit bodies, connectors, and hubs, depending on how you're running the conduit.

Where to Find Them

You can find these items at:

Electrical Supply Houses

This is your best bet. They'll have the largest selection and knowledgeable staff.


Home Improvement Stores (e.g., Home Depot, Lowe's)

They carry basic weatherproof enclosures and switches, but the selection may be limited.

Online Retailers (e.g., Amazon, Grainger)

Good for price comparison and finding specific items, but make sure you're buying from reputable sellers and check reviews.

Specific Product Examples (to give you search terms)



Weatherproof Enclosure

"NEMA 3R (or NEMA 4) enclosure 2-gang"

2-Pole Toggle Switch

"20 amp 2-pole toggle switch," "30 amp 2-pole toggle switch" (make sure it's rated for 240V)


Weatherproof Cover Plate

"Weatherproof toggle switch cover plate," "Weatherproof switch cover 2-gang"

Conduit Fittings

"1 inch (or 3/4 inch) PVC conduit body," "1 inch (or 3/4 inch) PVC weatherproof connector"

Important Considerations & Best Practices



Grounding

Proper grounding is essential for safety. Make sure the enclosure is properly grounded according to the National Electrical Code (NEC). Run a ground wire from the service panel to the well site and bond it to the enclosure and the pump.

Overcurrent Protection

You mentioned a disconnect switch at the well. Make sure the circuit is
already protected by a circuit breaker (or fuses) at the service panel. The disconnect switch is for local shut-off, not overcurrent protection.

Voltage Drop (VD)

Good job planning for voltage drop by using #10 wire. Calculate the VD based on the distance and pump current to ensure it's within acceptable limits (typically 3% or less).

Conduit Size

1" PVC is certainly overkill for two #10 wires, but if you're already planning to use it and you're not worried about cost, it will make pulling the wires much easier. 3/4" is usually plenty for that gauge of wire.


Licensed Electrician

While you seem to have a good understanding of the basics, consider consulting with or hiring a licensed electrician. They can ensure the installation meets all applicable codes and is done safely. Especially since it involves water and electricity!

National Electrical Code (NEC)

Follow all applicable requirements of the NEC. Article 430 covers motors, motor circuits, and controllers.


Local Codes and Permits

Check with your local authorities for any specific requirements, permits, or inspections that may be needed.

In summary:
Yes, what you're describing is readily available. Focus on finding a weatherproof enclosure, a 2-pole switch with the appropriate amperage rating, and the necessary conduit fittings to complete the installation safely and in accordance with electrical codes. Remember safety first, and consider hiring a professional electrician if you're unsure about any part of the process. Flag for review
