MCB Price & RCCB Replacement Cost Singapore
Quick answer: MCB and RCCB replacement cost
FixMove Singapore diagnoses faulty MCBs and RCCBs and scopes distribution-board upgrades before quoting. In Singapore, a single MCB replacement is from S$80 and an RCCB replacement is from S$150. A full DB board upgrade starts from S$380 for 6-way, S$580 for 12-way and S$780 for 18-way, plus S$40 per MCB. The circuit is diagnosed first, and regulated work is assigned to an EMA-licensed LEW where required.
What FixMove does
FixMove (registered ALL-IN-ONE FIX & MOVE, UEN 53505530K) comes to you anywhere in Singapore — your HDB flat, condo, office or shop. There is no counter to visit. One number covers eight kinds of work: aircon, plumbing, electrical, handyman, installation, moving, renovation and full-house customisation. We are open 24 hours, Monday to Sunday, and where the work is regulated we arrange the appropriately licensed person.
Visit charges: A S$10 fuel surcharge applies to every visit. No additional standard call-out or inspection fee applies. Urgent service or a customer-requested appointment time adds one S$30 fee, subject to technician availability and confirmation. The S$30 is a separate service fee. Repair, diagnostic labour and materials are quoted separately; work starts only after customer approval.

A breaker that won't reset, an RCCB that keeps tripping, or a scorched MCB is a safety issue — not a DIY job. We test the board first, then replace only the faulty MCB or RCCB (or upgrade the whole board if it's at the end of its life), with the cost quoted upfront.
MCB / RCCB & DB board pricing
Indicative ranges; final price confirmed after the technician inspects your board — any scope change requires written customer approval.
| Service | Indicative price |
|---|---|
| Diagnosis (why it's tripping) | from S$80 |
| Single MCB replacement | from S$80 |
| RCCB / ELCB replacement | from S$150 |
| Full DB board upgrade — 6 / 12 / 18-way | S$380 / S$580 / S$780 |

Board upgrades add S$40 per MCB. Diagnostic labour is quoted separately unless the written quote expressly states a credit.
MCB price or RCCB cost: what this page quotes
This is the specific price route for diagnosing and replacing one faulty MCB or RCCB/ELCB. If the whole distribution board needs replacement, use the DB box upgrade cost page; for prices across other electrical jobs, use the electrician cost guide. A trip may be caused by an appliance or circuit fault, so a breaker is replaced only after diagnosis identifies it as faulty.
MCB vs RCCB — what's failing?
MCB (overload protection)
Protects each circuit from overload and short-circuit. A worn or scorched MCB is swapped like-for-like.
RCCB / ELCB (shock protection)
Trips on earth leakage to protect against shock. A faulty RCCB — or a real leakage fault — needs a licensed check.
Repeated tripping
Often a faulty appliance or circuit, not the breaker. We diagnose first so you don't replace a healthy part.
Old / full DB board
If the board is ageing or has no spare ways, a 6/12/18-way upgrade is the cleaner long-term fix.
Why not just keep resetting it?
A breaker trips to protect the circuit — forcing a faulty MCB or RCCB back on, taping it up or bypassing it can create shock or fire risk. The board and affected circuit should be checked first; any regulated electrical work is assigned to an EMA-licensed LEW where required.

Frequently Asked Questions
What is the MCB price and RCCB replacement cost in Singapore?
A single MCB replacement is indicatively from S$80 and an RCCB from S$150, including the part and labour. A full DB board upgrade is S$380 (6-way), S$580 (12-way) or S$780 (18-way), plus S$40 per MCB. The final price and any LEW requirement are confirmed before work.
What is the difference between an MCB and an RCCB?
An MCB protects a circuit from overload and short-circuit. An RCCB or ELCB trips on earth leakage to protect against electric shock. Repeated tripping or a device that will not reset needs an electrical safety check; regulated work is assigned to an EMA-licensed LEW where required.
My breaker keeps tripping — do I need a new one?
Not always. Repeated tripping is often a faulty appliance or circuit, not the breaker itself. We diagnose first from S$80 and only replace the MCB or RCCB if it is genuinely faulty.
Is RCCB protection required in Singapore?
RCD or RCCB protection requirements depend on the installation and applicable rules. Do not bypass a device that will not reset; the circuit and board should be checked by an appropriately licensed worker.
