Sized against ABYC E-11. The design current is the part's continuous draw. The length is one way; voltage drop includes an equal-length return.

Run-length and manufacturer assumptions

The editable example uses 3.048 m (10 ft) runs unless a shorter run is stated. Metric overviews round these to 3 m. Adapt the parts and lengths to your installation before choosing cable and protection.

Which TILE charger is this?

SC-TILE-20 is Scanstrut's dual-USB-C interior charger with a black bezel. SC-TILE-21 has a stainless bezel and the same electrical specification. These differ from the USB-A/C SC-TILE-10/11 models.

Scanstrut's product page describes USB-C charging up to 36 W on a 12 V system or 60 W on 24 V. These output values are not the DC supply demand.

How is it represented in Crimp?

The manufacturer's Rev B instructions specify 10–32 V DC and 6 A maximum input. Crimp budgets that maximum at either nominal voltage, without assuming a fixed-power conversion curve. Actual consumption varies with connected devices. Two hours of daily use is editable; standby draw below 0.1 W is not separately simulated.

How do I wire and mount it?

Connect red to protected DC positive and black to negative. Preserve the supplied 18 AWG leads; protect the leads and any extension. Rev B requires suitable protection without specifying a fuse rating, so Crimp's displayed fuse is a planning result.

Use a dry interior location, away from water and hazardous/flammable atmospheres. The mounting cutout is 29 mm; check rear clearance and the manufacturer's template. The two USB-C sockets are device outputs, not battery-charging terminals.

Sources and sizing method

Equipment specifications. Model details, ratings and terminal roles come from the catalog. Check your unit’s label and current manufacturer documentation for its exact revision.

Example sizing. Sized against ABYC E-11 — the US reference, and what Transport Canada accepts as an alternative to TP 1332 for pleasure craft under 24 m. Results use the example current and run length shown above. Set your actual equipment, lengths and installation conditions in Crimp before choosing hardware.
