OCPP Tool vs Wire Size & Ampacity Calc

OCPP Tool is a lightweight, fully local utility for commissioning EV chargers over Bluetooth using the BluFi protocol — no account, no cloud, and no data collection. Connect to a charger over Bluetooth and configure everything on-site: • Scan & connect — discover nearby BluFi-enabled chargers and connect in seconds, with live signal strength. • Secure channel — an encrypted handshake (Diffie–Hellman key exchange + AES) protects every command sent to the charger. • WiFi provisioning — configure Station mode (SSID, password, BSSID) or SoftAP mode, or scan the charger's nearby WiFi list and pick a network. • OCPP setup — write the OCPP WebSocket URL and ChargePoint Identity straight to the charger. • Cellular & network — set the LTE APN and choose the network preference (Auto / Ethernet / WiFi / 4G). • Status at a glance — read the device firmware version, WiFi connection status and live network state. • Custom data — send and receive raw payloads for advanced diagnostics. Built for installers, field technicians and developers who need a fast, reliable, offline way to bring chargers online. Privacy first: OCPP Tool has no backend and makes no network requests. Everything you enter is sent only to the charger over Bluetooth. Nothing is collected, stored or uploaded.

Size conductors the way the code book does — without flipping pages. Pick NEC or IEC, enter the load, set the real conditions, and read the minimum conductor size on one screen. WHAT IT DOES - NEC (NFPA 70) Table 310.16 ampacities: copper and aluminum, 60/75/90 °C columns, 14 AWG to 500 kcmil - IEC 60364-5-52 method C ampacities: copper, PVC or XLPE, 1.5 to 300 mm² - Ambient-temperature correction and grouping adjustment applied automatically - 125 % continuous-load design current - Suggested breaker from the standard ladder, small-conductor caps included - Pro: full derating breakdown, conduit-fill summary (NEC Ch. 9 Table 1), voltage-drop cross-check, history and one-page PDF export BUILT FOR THE FIELD Big glove-friendly keys, an Outdoor Bright theme for direct sunlight, and everything works offline. PRIVACY Everything stays on your phone. No account, no ads, no tracking. A planning aid, not a substitute for the code — always confirm results with your local code authority and the current edition. PRO UNLOCKS: both NEC and IEC standards, full derating detail, conduit fill, voltage-drop checks, history and PDF export.
