Polycab Wire Price List Bangalore: FR vs FRLS vs FRLS-H Explained
Summary
- What the Grades Mean: The difference between FR, FRLS, and FRLS-H wires is smoke toxicity in a fire. FRLS-H is safest, releasing minimal non-toxic smoke and protecting both people and electronics.
- What to Use: For homes, FRLS-H (or FR-LSH) is the best choice for all circuits, especially for high-load appliances like ACs and geysers. It meets the highest safety standard (IS 17048).
- The Biggest Risk: Choosing the right wire grade is useless if the product is counterfeit—a common problem in Bangalore. Fake wires use substandard materials and are a major fire hazard.
- How to Buy Safely: To guarantee safety, source 100% genuine, ISI-certified wires from a trusted platform. HomeRun delivers authentic Polycab and Finolex wires from authorized dealers in 60 minutes across Bangalore.
You're sitting with your electrician, going over the wiring plan for your new home or renovation. He quotes you three different wire grades — FR, FRLS, FRLS-H — at noticeably different price points. You nod along, but inside you're wondering: what does any of this actually mean, and is the price difference genuinely justified?
You're not alone. On forums across the internet, homeowners and even experienced electricians debate the same thing: "go for FRLS if you want to finish it in a manageable budget" versus "go for FRLS-H if you're not worried about cost." But "not worried about cost" isn't useful advice. You need to know why the grades differ — and when the price premium actually protects you.
This guide breaks it all down: the technical differences between FR, FRLS, and FRLS-H, where each grade is mandated by Indian building codes, and a clear Polycab wire price list for Bangalore so you can make an informed decision before the wiring begins.
Decoding the Alphabet Soup: FR, FRLS, and FRLS-H Explained
All three grades are flame-retardant — meaning they're designed to slow or stop fire from spreading along the wire. But the key differences lie in what the wire emits when it burns, which turns out to matter far more in a real fire scenario than the flame itself.
FR (Flame Retardant)
FR wire uses standard PVC insulation with flame-retardant additives. It will resist ignition and slow fire propagation, but when it does burn, it releases dense black smoke and significant levels of halogen gases (primarily hydrogen chloride). These gases combine with moisture in your eyes, throat, and lungs to form hydrochloric acid — extremely corrosive and dangerous.
In a building fire, thick black smoke is often the primary cause of casualties, not the flames. FR wire satisfies the baseline IS 694 standard and is the most affordable option, but it's best suited for well-ventilated, low-risk circuits only.
FRLS (Flame Retardant Low Smoke)
FRLS wire uses a modified PVC compound that reduces smoke density and halogen gas emission compared to basic FR. Visibility in a fire scenario can be maintained up to 60%, and acid gas content is reduced to around 20% — a meaningful improvement. It still complies with IS 694 but with more stringent smoke and toxicity parameters.
FRLS is the practical middle ground: better safety than FR, still cost-accessible. The National Building Code (NBC) recommends FRLS for multi-storeyed buildings (above 15 metres) and public spaces where evacuation paths must remain visible.
FRLS-H / FR-LSH (Flame Retardant Low Smoke Halogen-Free)
This is where the engineering changes fundamentally. FRLS-H (also written FR-LSH, HFFR, or LS0H — all referring to the same category) replaces the PVC compound entirely with halogen-free polymer blends, typically polyolefins. The result: virtually transparent white smoke and near-zero toxic gas emission when the wire burns.
This is important because halogen-free wires don't just protect people — they protect sensitive electronics and structural components from corrosive gas damage. FRLS-H complies with IS 17048, the stricter Indian standard for halogen-free flame retardant cables, as well as international benchmarks like IEC 60332 (flame propagation) and IEC 60754 (halogen gas emission).
CPWD (Central Public Works Department) mandates FRLS-H for critical infrastructure — hospitals, metro stations, data centres, government buildings. It's also the responsible choice for any enclosed living space in your home.

Is the Upgrade Worth It?
Looking at the options, upgrading from a basic FR wire to a safer FR-LSH grade represents a modest increase in cost for a significant gain in safety. For a 90-metre coil covering a standard room circuit, the price difference is a small fraction of any renovation budget.
Put it this way: the wiring in your home is typically inside walls for 20–30 years. The incremental cost of upgrading to FRLS-H is a rounding error in any renovation budget. The protection it provides is not.
For high-load applications — ACs, geysers, kitchen circuits — the Polycab FRLS-H Single Core Wire on a 300m coil is the specification-grade choice that meets CPWD mandates and IS 17048 compliance. If your project involves a contractor, consultant, or CPWD specification sheet, this is what they're asking for.
The Polycab Maxima+ Green Wire HR FR-LSH LF (the "LF" stands for Lead-Free) adds another layer: it's halogen-free and lead-free, making it the cleanest environmental and safety profile available in a residential wire. If you're thinking about legacy toxin reduction beyond just fire performance, this is the wire.
The Counterfeit Wire Problem in Bangalore — and Why It Matters More Than Grade
Here's something that doesn't get discussed enough: choosing the right wire grade means nothing if the wire you actually receive isn't what it says on the label.
Bangalore's construction supply chain — like most of India's — has a well-documented counterfeit materials problem. Reddit discussions from Bangalore homeowners are littered with comments like "I've lost my trust in local electricians" and "most electricians don't even bother to wire simple circuits properly." A significant part of this trust deficit comes not from the electrician's skill, but from the materials they source — often from grey-market distributors where counterfeit or substandard wire is common.
Fake wires can use aluminium-clad copper conductors instead of pure copper, undersized conductor cross-sections, recycled PVC with no real flame-retardant properties, and fake ISI markings printed on the sheath. You'd never know until something goes wrong.
This is where HomeRun solves a problem that product specs alone can't.

Quick Reference: Wire Gauge by Application
Still unsure which gauge you need for each circuit? Here's a practical map for standard Indian homes:
| Wire Gauge (sq. mm) | Typical Application |
|---|---|
| 1.0 sqmm | Lighting circuits — LEDs, tube lights, doorbells |
| 1.5 sqmm | Ceiling fans, exhaust fans, 5A plug sockets |
| 2.5 sqmm | General 15A power sockets, TVs, computers |
| 4.0 sqmm | Air conditioners (up to 1.5 ton), water pumps |
| 6.0 sqmm | Geysers, heavy-load sub-mains, main supply lines |
A few common wiring mistakes that Bangalore homeowners discover too late:
- Undersizing for ACs and geysers: Running a 1.5mm wire to a 1.5-ton AC is one of the most common causes of insulation meltdown and tripped MCBs. Use 4mm minimum.
- Using FR wire in wet areas: Bathrooms and kitchens have humidity levels that accelerate PVC degradation. FRLS-H or FR-LSH is the right call here — sealed, halogen-free insulation holds up significantly better over time.
- Buying from unauthorised sources: ISI marking on the sheath is not proof of authenticity. Your safest guarantee is buying from an authorised channel with a verifiable supply chain.
Don't Compromise on Wire Grade — or Wire Source
The hierarchy is clear: FRLS-H > FRLS > FR, on everything from smoke toxicity to gas emission to long-term insulation integrity. For modern homes in Bangalore, FR-LSH should be the floor for any inhabited space, and FRLS-H the specification for high-load circuits, kitchens, and compliance-critical projects.
But no grade on the label matters if the wire inside the wall isn't what it claims to be. That's the more urgent problem in Bangalore's market right now. Verifying your wire source is as important as specifying the right grade.

Frequently Asked Questions
What is the main difference between FR, FRLS, and FRLS-H wires?
The primary difference lies in their reaction to fire, specifically the smoke and fumes they emit. FR wire produces dense, toxic smoke. FRLS wire generates less smoke, improving visibility. FRLS-H wire is the safest, producing very little, non-toxic, and non-corrosive smoke, which is critical for safe evacuation and protecting electronics.
Why is FRLS-H wire the safest choice for a home?
FRLS-H wire is safest because it is halogen-free. In a fire, it doesn't release corrosive halogen gases (like hydrogen chloride) that can severely damage your lungs and sensitive electronic equipment. Its low smoke emission also ensures that escape routes remain visible, which is often the most critical factor for survival.
Can I use basic FR wire in my house to save money?
While FR wire is the most affordable and meets basic safety standards (IS 694), it is not recommended for enclosed living spaces. The dense, toxic smoke it releases in a fire poses a significant risk. Upgrading to a safer FR-LSH or FRLS-H wire for a slightly higher cost provides a crucial safety margin that is well worth the investment.
What type of wire is required for high-rise buildings in India?
The National Building Code (NBC) of India recommends FRLS (Flame Retardant Low Smoke) grade wires for all multi-storeyed buildings taller than 15 metres. For critical public infrastructure like hospitals and data centres, the Central Public Works Department (CPWD) mandates the even safer FRLS-H grade, which is also the best practice for residential high-rises.
How can I be sure the electrical wires I buy are genuine?
The most reliable method is to purchase from authorized dealers or trusted e-commerce platforms like HomeRun, which guarantee a verifiable supply chain. Counterfeit wires often have fake ISI markings and use substandard materials but can be hard to spot visually. Buying from a reputable source ensures you get a genuine, certified product that performs to its safety specifications.
Are FR-LSH and FRLS-H the same thing?
Yes, FR-LSH and FRLS-H are different acronyms for the same high-safety wire. Both stand for Flame Retardant, Low Smoke, Halogen-Free. You might also see it referred to as HFFR (Halogen-Free Flame Retardant) or LS0H (Low Smoke Zero Halogen). All refer to wires made with halogen-free compounds that offer the highest level of fire safety.
