On a twin-vehicle pitch, one pedestal serving two bays removes a foundation, a trench run, and a connection point from every site. The GRWE1002520D-R is the 250 mm tier of the GRWE100 series, built for projects where two vehicles connect at one column and where the power configuration per pitch runs higher than a standard layout. This guide covers what the model is, how it compares with the 200 mm tier, how a 4 to 7 kW configuration is planned, and what changes when a single unit serves two pitches.
In Short
The GRWE1002520D-R is a dual-sided water and power pedestal with a 1000 x 250 x 200 mm envelope, four sockets, two frost-resistant faucets, and a 250 mm enclosure that carries 25 percent more internal width than the 200 mm tier. Choose it when a pitch serves two vehicles, when the power configuration per pitch is 4 kW or higher, or when metering and extra protective devices have to fit inside the column. Choose the GRWE1002020D-R when standard single-vehicle pitches and a standard power configuration are enough.
Key Takeaways
- One column covers two bays, so foundations, trench runs, and cable routes drop from two to one.
- The 250 mm enclosure adds 25 percent internal width over the 200 mm tier, allowing larger protective devices or metering inside the column.
- A 4 to 7 kW rating describes the load one pitch supports at a time, and the incoming supply has to be sized for both bays running together.
- Breaker rating, cable current-carrying capacity, and socket rating are matched as a set, with protective devices operating before the cable reaches its thermal limit.
- The unit is positioned on the boundary between the two bays it serves, keeping cable reach short and balanced on both sides.
What the GRWE1002520D-R Is Built For
Reading the Model Designation
The GRWE1002520D-R follows the naming pattern used across the series. GRWE100 indicates the series and column height (a 1000 mm column). The figures that follow describe enclosure length and internal layout, while the -R suffix marks the configuration used in this series. Read as a whole, the designation states column height, enclosure length, and internal capacity class before opening a drawing.
The 250 mm Enclosure and What It Changes
All three tiers share a 1000 mm column height and 200 mm section depth. Length sets internal capacity (200 mm, 250 mm, and 300 mm options), which decides which electrical configurations a project can specify. The 250 mm body carries 25 percent more internal width than the 200 mm tier. On projects specifying higher power per pitch, separate protection for each output, or internal metering modules, that extra width keeps the specification buildable without needing a separate cabinet.

What the Extra Width Allows Inside the Column
The additional 50 mm of internal width matters when a project specifies any of the following:
- Higher power capacity per pitch, requiring larger protective devices.
- Separate protection for each output, instead of one device covering both sides.
- Metering or control modules mounted inside the enclosure.
- More generous wiring space, shortening on-site maintenance time.

Which Model Fits Which Project
| Project Situation | Suggested Model |
|---|---|
| Standard dual-vehicle pitches with a standard power configuration | GRWE1002020D-R |
| Pitches with higher power capacity requirements | GRWE1002520D-R |
| Additional circuit components or metering specified inside the enclosure | GRWE1002520D-R |
| Very high component count or the widest internal configuration | GRWE1003020D-R at 300 mm |
The comparison with the wider tier is set out in our guide to choosing an outdoor power pedestal, and the campground scope is covered under RV parks and campgrounds.

Planning Power Capacity From 4 kW to 7 kW
Power rating is one of the first decisions in a campground specification, determining what guests can run and what has to be installed behind the pedestal.
What Each Rating Band Supports
A power rating describes the load a pitch can support at one time across appliances like air conditioning, refrigeration, cooking equipment, and personal electronics.
| Rating Band | Approximate Current at 230 V Single Phase | Typical Load Profile |
|---|---|---|
| 4 kW | About 18 A | Air conditioning plus basic appliances |
| 5 kW | About 22 A | Air conditioning plus several appliances at once |
| 6 kW | About 26 A | Multiple heavy loads, larger motorhomes |
| 7 kW | About 32 A | Full load profile, largest motorhomes, and long-stay guests |
Matching the Breaker, Cable, and Socket
Three elements must be matched as a set: protective device breaking capacity, cable current-carrying capacity, and socket rating. The device must operate before the cable reaches its thermal limit. As power ratings rise, cable cross-sectional area increases accordingly. Exact sizes are confirmed with the JIYA technical team against local codes.
Sizing the Supply for Two Bays at Once
For a dual-vehicle pedestal, the total demand is the combined load of both pitches:
- The incoming supply is sized for both bays running simultaneously.
- Voltage drop increases with current and distance, making run length critical.
- Upstream distribution design must carry the total connected load across shared pedestals.
Our guide to electrical service sizing for an RV park details full calculation steps, while our RV water and electric pedestal range displays full series alignment.
What to Confirm Before Ordering
| Item | Why It Matters |
|---|---|
| Target power per pitch | Determines protective device and cable sizing |
| Combined load for both bays | Determines incoming supply requirement |
| Cable run length | Affects voltage drop, especially at higher power |
| Local code requirements | Governs earthing, protection, and cable sizing |
| Protection arrangement | Whether each circuit needs separate protection |
| Metering requirement | Affects internal component count and enclosure length |
Installing One Pedestal Across Two Pitches
Positioning on the Bay Boundary
The pedestal normally sits on the boundary between the two bays it serves, keeping cable runs to both vehicles short and balanced. Always verify reach to the furthest connection point on each side before finalizing positioning.
Mounting Options and Lead Time
| Method | Description | Typical Lead Time |
|---|---|---|
| Surface mounting | Expansion bolts into a prepared base or slab | Short |
| Concrete embedding | Poured base with pre-set anchors, cured to strength | 3 to 5 days |
Commissioning Checks After Connection
- Fix the column to the foundation and confirm it is vertical and secure.
- Connect the water supply and check for leaks before closing.
- Connect electrical supply per site distribution design.
- Verify earthing continuity at 0.1 ohm or less.
- Verify insulation resistance at 10 megohms or more at 500 V.
- Test leakage protection devices for correct operation.
- Confirm socket polarity and voltage at each outlet.
- Run a load test to confirm stable operation.
One Pedestal Against Two Single Units
| Item | Two Single-Vehicle Pedestals | One GRWE1002520D-R |
|---|---|---|
| Units per two bays | 2 | 1 |
| Foundations | 2 | 1 |
| Trench runs | 2 | 1 |
| Cable routes | 2 | 1 |
| Positioning | Within each single bay | On the boundary between both bays |
| Cable reach check | One side only | Both sides |
| Supply sizing | Single pitch load | Combined load of both pitches |
| Commissioning checks | Per unit | Per output, both sides |
Maintenance for a Two-Bay Pedestal
Weekly checks cover socket protective covers, housing condition, lighting, and locks. Monthly checks inspect internal cables, terminal blocks, leakage test buttons, and dust removal.
Seasonal checks inspect coastal enclosure surfaces, water compartments, and post-maintenance device tests. View our full pedestal maintenance checklist for complete maintenance schedules. Keeping monthly checks on schedule minimizes operational risks when one unit serves two pitches.
