Will any MCB fit in a consumer unit?
Not all mcbs fit all consumer units – they should all be standard, but they aren’t always. Not heard of Steeple as a brand/manufacturer, so can’t advise on what’ll fit with what. You could split the tails with a double pole service block and run additional tails to a new smaller cu.
Are Type 2 and Type B MCB the same?
The trip times of the MCBs are different, and they sometimes overlap. Type B equates to Type1/2. Type C equates to Type2/3.
What is the difference between Type C and Type B MCB?
Type B devices are designed to trip at fault currents of 3-5 times rated current (In). For example a 10A device will trip at 30-50A. Type C devices are designed to trip at 5-10 times In (50-100A for a 10A device). Type D devices are designed to trip at 10-20 times In (100-200A for a 10A device).
What type of MCB is used in domestic?
The best-suited type of MCB for domestic appliances, where the current load is medium, is type C. Type C MCB trips off when the flow of current is 5-10 times more than normal. Type D MCB has a high resistance as they can withstand up to 10-20 times the current rate.
Can you mix MCB brands?
Or put another way: only use manufacturer approved parts, don’t mix brands of devices or control items. Each manufacturer of electrical switchgear designs and tests its own products for use in combination with each other, not with other brands.
How do I choose the right MCB?
First, you should determine the total current of the circuit. Then, you should select the proper MCB. The current rating of MCBs should not be greater than the cable current carrying capacity. It should also be greater than or equal to the maximum current that the system is expected to carry.
What are type B circuit breakers used for?
Type B circuit breakers are designed to trip if the current flowing through hits between three and five times the recommended maximum or ‘rated load’. This is the most sensitive type of MCB, designed for domestic applications, and low voltage commercial settings where any current surges are likely to be small.
What is a Type C MCB used for?
C-Curve MCB ‘C’ Curve MCB is used for the protection of circuits with equipment that cause surge current i.e. low-HP motors used for air-conditioners, small mono block and submersible pumps with mainly Inductive Load.
