Trending electrician tools
Cable size, voltage drop, max demand, Zs/R1+R2, circuit schedules and AI panel tools, but with heaters, dehumidifiers, fans, portable AC and temporary distribution built into the workflow.
Check whether a 110V site transformer can realistically power temporary heaters, dehumidifiers, fans or drying kit without overload or ugly voltage drop.
For construction sites, drying contractors and hire desks using 110V heaters or 110V drying equipment.
Estimate cumulative leakage from compressors, dehumidifiers, portable AC, heaters, pumps and long wet leads before stacking everything behind one RCD.
Use it when drying or cooling equipment trips randomly or when several items share one RCD/RCBO.
Size a generator for portable AC, dehumidifiers, fans and heaters with a start-current allowance rather than only running watts.
For event sites, emergency cooling, flood drying and temporary power jobs.
Allocate single-phase heaters, dehumidifiers, fans and portable AC units across L1/L2/L3 to reduce imbalance and nuisance trips.
For 32A, 63A and 125A temporary distribution boards with mixed 230V loads.
Estimate voltage drop over long leads for heaters, air movers, dehumidifiers and portable AC, with compressor start warnings.
A planning aid, not a certification cable design package.
Estimate PSCC or PEFC from Ze and voltage, compare against device breaking capacity, and draft a quick test-sheet note.
For competent persons checking prospective fault current, breaking capacity and temporary distribution assumptions.
Check a measured Zs value against an entered device limit, with optional 80% rule headroom and clear pass/check wording.
For reviewing Zs results on MCB/RCBO circuits before recording or investigating a circuit.
Use the adiabatic equation shape to compare fault current, disconnection time, k factor and CPC size as a planning aid.
For competent review of CPC adequacy where final design still needs current BS 7671 tables and site data.
Stack ambient temperature, grouping, insulation and installation correction factors to see whether corrected Iz still covers load current.
For quick cable-capacity sanity checks before final BS 7671 cable selection.
Review x0.5, x1 and x5 RCD trip-time readings and produce a clear pass/check prompt for the job file.
For checking recorded RCD results before deciding whether to retest, investigate or replace.
Turn L-N, L-E and N-E insulation-resistance readings into practical next-step notes for damp circuits, appliances and fault finding.
For electricians reviewing low or borderline MΩ readings without treating a web tool as certification.
Estimate continuous heater, dehumidifier and socket-load pressure on a ring final circuit, including spurs, adaptors and run-time warnings.
For temporary heaters and drying equipment connected to ordinary socket circuits.
Paste circuit and test-sheet notes to flag missing Zs, R1+R2, IR, RCD or breaker details and generate a cleaner copyable schedule.
For tightening up temporary DB schedules, EICR notes and job-file records before handover.
High-demand UK cable and voltage-drop calculator reframed for temporary heaters, fans, dehumidifiers and portable AC.
For quick planning before verifying against current regulations and installation conditions.
Estimate realistic demand where heaters, compressors, fans and drying equipment do not all peak together.
A demand-planning aid for temporary climate equipment and mixed commercial loads.
Calculate expected Zs from Ze and R1+R2, or derive R1+R2 from measured Zs for circuit assessment notes.
For competent persons recording or checking circuit test values.
Create a printable schedule for boards feeding temporary heaters, dehumidifiers, fans, drying kit or AC.
Use after a board photo, site walk-round or temporary DB layout.
Draft C1/C2/C3/FI-style wording for common observations around overloaded sockets, damaged reels, RCD issues and temporary HVAC equipment.
A wording assistant only. It does not issue certificates or decide compliance for you.
Select a likely temporary connection class based on load current, voltage, environment and duty cycle.
For heaters, dehumidifiers, fans, portable AC and temporary distribution planning.
A selector aid for AC, dehumidifiers, inverter drives, electronic controls and mixed temporary HVAC equipment.
For discussing protection type with a qualified electrician or designer.
Estimate whether fan or compressor starting current is likely to be harsh for a B, C or D curve MCB.
For compressor/fan start trips and generator-fed temporary power.
Lay out a temporary board for heaters, drying equipment, fans, portable AC and lighting, with circuit groups and notes.
For competent persons planning temporary distribution, not for DIY live work.
A practical visual checklist for plugs, sockets, reels, commando connectors and temporary HVAC leads before use.
For site checks before plugging in temporary heaters, drying kit or portable AC.
Upload a board photo and create a draft circuit map, breaker list, RCD group notes and temporary HVAC suitability questions.
A triage tool. It does not replace inspection, testing or opening a panel by a competent person.
Use a normal phone photo for a thermal-style risk overlay based on visible clues, or upload true thermal imagery when available.
Normal cameras cannot measure temperature. This flags visual risk clues and creates a pseudo-thermal check map.
Upload or type nameplate details from heaters, dehumidifiers, fans or AC units and extract voltage, current, watts, phase and IP hints.
Use the extracted values to pre-fill generator, RCD and voltage drop tools.
A photo-led checklist for coiled reels, discolouration, cracked plugs, loose strain relief and overloaded adaptors.
Designed around visible signs only, with clear escalation language.
Use a room photo plus measurements to draft dehumidifier and air mover placement notes for drying jobs.
Useful for pre-site scoping, not a moisture survey.
Draft a method statement outline for temporary heating, drying, ventilation or cooling equipment on site.
Editable draft for competent review, not legal or safety sign-off.
Turn observations into a clear remedial scope, materials prompt and temporary equipment restriction note.
For drafting, not certification.
Create a compact pack with assumptions, equipment list, circuit plan, risk flags and NHS category references.
For hire desks, FM teams and contractors turning a calculation into a client-facing note.
