Adiabatic Equation Calculator vs iCertifi Cloud Pro

Adiabatic Equation for calculating the minimum cpc (circuit protective conductor) and earth minimum csa sizes of earthing conductors, S = √(I²t) / k. This Adiabatic Equation Calculator takes into account the following parameters: t = Disconnection time (seconds). k = Conductor k value (From BS 7671 tables). la = Fault current (PEFC in Amps). I² = la x la. Results with the minimum CSA mm². Values of K are obtained from the tables within BS 7671: - Table 54.2 : Conductor not incorporated in a cable and not bunched with cables. - Table 54.3 : Conductor incorporated in a cable or bunched with cables. - Table 54.4 : Sheath or armour of a cable. - Table 54.5 : Steel conduit or trunking. Disconnection times (t) are obtained from the maximum operating time/current characteristics tables within BS 7671: - Fig 3A2 (a,b) : BS 3036 semi-enclosed fuse. - Fig 3A3 : (a,b) : BS 88-2.2. - Fig 3A4 : BS EN 60898 / 61009-1 MCB/RCBO type B. - Fig 3A5 : BS EN 60898 / 61009-1 MCB/RCBO type C. - Fig 3A6 : BS EN 60898 / 61009-1 MCB/RCBO type D. - BS 1361 Fuse. How to use the Adiabatic Equation App: 1) Input your voltage value. 2) Input your Zs value. 3) Select protective device. 4) Select protective device rating. 5) Select conductor type. 6) Select conductor material. 7) Tap calculate.

Photograph the board — iCertifi Cloud Pro reads every circuit and fills the schedule for you. EICR, EIC and Minor Works certificates to BS 7671, on iPhone, iPad and Mac. Start a certificate on your iPhone, continue on your iPad, finish on your Mac. Everything is backed up to the cloud with end-to-end encryption, so your work survives a lost, stolen or replaced device. BOARD VISION — POINT, SHOOT, DONE Take one photo of the distribution board. Board Vision detects the devices, circuit order and layout, and fills your circuit schedule in about 30 seconds. What used to be 20 to 45 minutes of typing out MCBs, ratings and labels is now a photo you check and confirm. TEST VISION — READINGS STRAIGHT OFF THE TESTER Photograph your test instrument's display and the readings are extracted and matched to the right circuit automatically. Any make, any model. No cables, no Bluetooth pairing, no transcription errors. SPARK AI — YOUR 24/7 TECHNICAL HELPLINE Instant answers on BS 7671, EICRs, testing procedure and observation coding, without leaving the certificate you are working on. COMPLIANCE CHECK Every certificate is checked automatically before you issue it, so mistakes are caught while you are still on site — not by the client, the assessor or your QS. WORKS COMPLETELY OFFLINE Certify with no signal, no laptop and no desktop software. Data uploads automatically the moment you reconnect. Built exclusively for Apple devices. CERTIFICATES INCLUDED - Electrical Installation Certificate (EIC) - Electrical Installation Condition Report (EICR) - Minor Electrical Installation Works Certificate - Three Circuit Minor Works - Domestic Installation Certificate - Electric Vehicle Charging Installation Certificate - Landlord Interim Report - Visual Inspection Report - Earthing & Bonding Certificate - Isolation Certificate - Danger Notice …and more NEW — CLIENT HUB Every customer in one place: their jobs, certificates and upcoming retests, grouped by client. Due work and reminders appear on the Dashboard the moment you open the app, so recurring contracts come back to you. TESTING TOOLS THAT DO THE MATHS - Zs calculations — auto-calculated for MCBs and RCDs, 100% or 80% options - Fuse calculator — 0.4s and 5s fuse Zs - BS 7671 regulation checks as you enter results - Split load RCD testing with multiple recorded times - Electrician's Toolbox — lighting calculator, fuse kA, thermal imaging and more - FLIR ONE thermal imaging — find faults without isolating the supply SPEED ON SITE - Template boards — save and reuse board configurations - Copy and paste boards between certificates - Smart Duplicate — reuse any previous certificate, omitting dates, signatures and test results - Smart Fill and Quick Fill — sections and common circuit values in one tap - Speech-to-text — dictate test results - Notes history, pre-filled defaults and searchable certificate types EICRs DONE PROPERLY - The Vault — nearly 500 prewritten observations with BS 7671 codes - Add photographs to document faults and observations - Digital circuit schedules with QR-encoded layouts - Printable EICR covers - Calibration certificate attachments for your tester records QS MONITORING AND REMOTE SIGNING Qualified Supervisors can review, approve and sign remotely, and flag issues live — useful for multi-engineer contracts and scheme assessments.
