15 HP, 240V DC motor has a full-load current (FLA) of approximately 55 Amperes.
Based on common DC motor data (such as NEMA standard tables often used in Canada), a 15 HP, 240V DC motor has a full-load current (FLA) of approximately 55 Amperes. For protection using a non-time delay fuse in Canada, the maximum permitted size is generally 150% of the full-load motor current. Motor FLA: 55 AMax Fuse Rating: \(55\text{A}\times 1.50=82.5\text{A}\)Standard Fuse Size: The next standard fuse size up, which would typically be a 90A or 100A non-time delay fuse (such as Class K5 or H), although 80A might be used if the motor FLA is slightly lower.

when a gfci is located outdoors flood zone, what type should it be? in canada
In Canada, the selection of a GFCI for an outdoor flood zone is a matter of meeting both the **Canadian Electrical Code (CEC)** requirements for wet locations and the physical realities of potential submersion. According to the CEC and standard safety practices for 2026, here is the type of GFCI you should install: ### **1. The Mandatory Rating: "Weather-Resistant" (WR)** Under **Rule 26-702**, all receptacles installed outdoors or in damp/wet locations must be **Weather-Resistant (WR)**. * **The "WR" Stamp:** Look for the "WR" symbol on the face of the outlet. * **Design:** These GFCIs are built with UV-stabilized plastics and corrosion-resistant metallic components to withstand rain, snow, and humidity better than a standard indoor GFCI. ### **2. The Flood Zone Consideration: "Submersible" vs. "High Elevation"** It is important to note that **no standard GFCI receptacle is rated for submersion.** If a GFCI is under water, it will likely fail or trip permanently. * **Elevation (The Best Practice):** In designated flood zones, the CEC and local building codes often require electrical outlets to be installed **above the Base Flood Elevation (BFE)**. If your area is prone to flooding, the "type" of installation matters more than the device: move the receptacle to a height where it is unlikely to be submerged. * **Dead-Front GFCI Option:** If the outlet *must* be in a low-lying area, a common strategy is to use a **Dead-Front GFCI** located in a high, dry area (indoors or higher up a wall) to protect a standard WR receptacle downstream. This allows you to reset the protection without wading into a flood zone. ### **3. The Enclosure: "In-Use" Weatherproof Cover** Even with a WR-rated GFCI, **Rule 26-702** requires an **Extra-Duty "In-Use" Cover** (also known as a bubble cover). * **Requirement:** The cover must be rated "Extra-Duty" if the receptacle is installed in a location where it is exposed to the weather. * **Function:** This allows the outlet to remain weatherproof even when a cord is plugged in. ### **4. Summary of Requirements for 2026** | Feature | Requirement | Reason | | --- | --- | --- | | **Device Type** | **GFCI + Weather-Resistant (WR)** | Corrosion and UV protection. | | **Cover Type** | **Extra-Duty "In-Use" Cover** | Protection while a cord is plugged in. | | **Protection** | **Class A GFCI** (5mA trip) | Mandatory for personnel protection. | | **Placement** | **Above Flood Level** | Standard GFCIs are not submersible. | --- ### **Blogger Labels** * **Weather-Resistant GFCI Canada,** * **CEC Rule 26-702,** * **Extra-Duty In-Use Covers,** * **Electrical Flood Zone Safety,** * **Outdoor Receptacle Requirements,** **Would you like me to check the specific "Base Flood Elevation" height requirements for electrical outlets in your specific municipality?**

With tariffs cut in Canada, perhaps China will break the ice for its big-selling EVs in North America through thawing relationships with our neighbors to the north.
